Need to erase as many bytes as the size to write.
The size to erase is expressed aligned on the page size.
(assuming the page_info.size is constant)
In case the page_info.size is lower than the size to write,
the next write operation will fail.

Add property mxicy,mx25r-power-mode to jedec,spi-nor binding for
controlling low power/high performance mode on Macronix MX25R* Ultra Low
Power flash devices.
- "low-power" configures the flash in ultra low power mode.
- "high-performance" configures the flash in high performance mode.

The commit switches flash area access from FLASH_AREA_ macros
to FIXED_PARTITION_ macros and to usage of DTS node labels,
to identify partitions, instead of label property.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Some SOCs, such as NXP's LPC family, expect a minimum write size of 512
bytes. Increase the EXPECTED_SIZE definition for flash driver test to
512 so that test can pass on these platforms.

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

Add a bunch of missing "zephyr/" prefixes to #include statements in
various test and test framework files.

In order to bring consistency in-tree, migrate all tests to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

The `size` property is expressed in `bits` unit.
The value should be calculated as bits to bytes conversion.

If a user has a 1GB external flash it is currently not possible
to configure this through DTS. To allow for such a configuration
we add an option which specifies the size in bytes not bits.
