For the parts of the simulator which are dedicated for the native
platforms (POSIX arch based):
* Refactor the parts that interacts with the host, so it is possible to
use it also with embedded libCs
* Enhance it with more options to allow:
* Keeping the content just in RAM
* Erasing the EEPROM file at exit
* Clearing the file at boot
* Also show in the command line help the default file name.
As part of this:
* Update the kconfig dependencies, so we allow building it with other
C libraries in the native targets
* Update the table in the native_sim docs to indicate all C libraries
are supproted now

Do not enable subsystem/driver shell modules by default and stop abusing
CONFIG_SHELL_MINIMAL, which is internal to the shell subsystem, to decide
when to enable a driver shell.
The list of shell modules has grown considerably through the
years. Enabling CONFIG_SHELL for doing e.g. an interactive debug session
leads to a large number of shell modules also being enabled unless
explicitly disabled, which again leads to non-negligible increases in
RAM/ROM usage.
This commit attempts to establish a policy of subsystem/driver shell
modules being disabled by default, requiring the user/application to
explicitly enable only those needed.

Quite a few of the drivers meant for the POSIX arch
interacted with the host directly, and will not
work when we use an embedded libC.
Until we fix them, let's add the appropriate
kconfig dependencies to avoid users trying to build them.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

Refactors all of the EEPROM drivers to use a shared driver class
initialization priority configuration, CONFIG_EEPROM_INIT_PRIORITY, to
allow configuring EEPROM drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The
exceptions are at2x and emul drivers which have dependencies on SPI,
I2C, or flash drivers and must therefore initialize later than the
default device priority.

This driver emulates a EEPROM device in flash.
Reworked implementation with modified flash layout.
The emulation represents the EEPROM in flash as a region that is a
direct map of the eeprom data followed by a region where changes to
the eeprom data is stored. Changes are written as address-data
combinations. The size of such a combination is determined by the
flash write block size and the size of the eeprom (required address
space), with a minimum of 4 byte.
The eeprom page needs to be a multiple of the flash page. Multiple
eeprom pages is also so supported and increases the number of writes
that can be performed.
The eeprom size, pagesize and the flash partition used for the eeprom
are defined in the dts. The flash partition should allow at least two
eeprom pages. For fast read access a rambuffer can be enabled for the
eeprom (by setting the option rambuf in the dts).

The default priority for I2C controller initialization is POST_KERNEL
60 (SPI 70), while the default priority for device configuration is
POST_KERNEL 50. Thus the EEPROM is being initialized before its
controller. While for this driver that wouldn't be an issue recent
changes mean the device lookup returns NULL before the device is
initialized.
Change the AT2X priority to 75 so it falls between the I2C and SPI
drivers and the default ethernet priority (80), since some ethernet
controllers may store the MAC address in EEPROM.

I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.
There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.
The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).
Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.
Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.
Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.
The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.
(Everything above is true for choices, menus, and comments as well.)
Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.
