DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

If the flash is used in 4-byte addressing, reading SFDP will fail after
a system reset if the flash isn't power cycled or hardware reset, since
Zephyr will try to use 3-byte addressing while the flash (still) expects
4-byte addressing.
This commit adds the ability to send a reset command to the flash as part
of initialization, which complements the existing reset-gpio
functionality, and is useful on low-pincount flashes which do not have a
hardware reset.

There are three types GD32 FMC.
GD32 FMC v1: its flash memory has 1 bank, page size is equal in the
bank, flash size is smaller than 512KB.
GD32 FMC v2: its flash memory has 2 banks. Page size equal within the
same bank but different between banks. Flash size can be up to 3072KB.
FMC v2 has two registers to control bank0 and bank1 separately.
GD32 FMC v3: its flash memory has 2 banks, use sector size as the
minimum operating unit, the sector size is not equal.

This adds flash driver for Renesas SmartBond(tm) family.
This technically uses QSPI controller but since default and most
commonly used configuration is to boot from external QSPI flash (DA1469x
do not have built-in flash) and that flash is mapped into memory space,
it can be represented as internal flash.

The current atmel sam flash driver was develop based on the cortex-m7
version of smart arm microcontroller. The driver support write
protection and cache functions which is not supported by other cortex-m
variants. This fixes current driver implementation and devicetree
entries for all sam variants.
Notes:
* The cortex-m3 doesn't have support erase pages flash command and
because of that the driver still not not compatible. Keep it disabled
until a patch be send. The hwinfo driver is not affected by this
restriction.
* The sam4l variation requires a specific driver because uses another
flash controller (flashcalw). Added another compatible to
differentiate and keeped node disabled until a driver be available.

Add some details to help new users learn how to manage the nodes
for compatibles corresponding to IP blocks on Nordic SoCs.
The focus is on IP blocks where the pinmux is configured in
devicetree. These typically have individual properties for each pin,
like a SCK pin on a SPI peripheral, which correspond directly to a
PSEL register value. These violate the usual devicetree convention of
using a 'foo-gpios <&gpioX ...>' phandle property and work in ways
that only make sense if you understand the underlying register map, so
it's worth explaining them a bit more carefully.
Skip these two bindings, which have no drivers: nordic,nrf-i2s.yaml,
nordic,nrf-pdm.yaml.

Most JEDEC NOR flash devices uses not only typical SPI mode
(MISO,MOSI,SCK and CS), but also QSPI mode (IO0,IO1,IO2,IO3,SCK and CS).
QSPI mode uses more data lines and as a result provide higher
throughput. If this were not enough, Nordic chips provide
hardware acceleration for read/write/erase functions, what
gives significant performance boost.
It does a lot of things "behind the scene", i.e when user has written
some data to the flash and would like to read them back, it has to wait
until the flash is ready by reading WIP bit in Status Register.
This driver does it automatically.

Some other things could probably be cleaned up (replacing 'GPIO node'

I kept things close to the original to avoid accidentally messing up.
