Add a check to avoid invalidating the cache when the latter is disabled.
Indeed, doing so can lead to a bus fault.

Refactors all of the on-chip flash drivers to use a shared driver class
initialization priority configuration, CONFIG_FLASH_INIT_PRIORITY, to
allow configuring flash 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.
Driver-specific options for SPI-based flash drivers are left intact
because they need to be initialized at a different priority than on-chip
flash drivers.

The STM32H7x flash has an integrated ECC that can correct single
errors and detect double errors. When a double ECC error is detected,
the DBECCERR1/2 flag is raised and there is a bus fault.
We now mask this bus fault and check the error flags. ECC errors are
logged with the offset of the data. Single ECC errors cause a warning
to be logged and double ECC errors return -EIO.
Fixes#33140.

definitions from device tree.

flash_write_protection_set() API was deprecated so driver
implementation interface is left behind as well.
This patch removes all implementation pointed by the interface
'struct flash_driver_api.write_protection'.

Flash write protection services were integrated into erase and write
procedures. This is step required for fixing following issue:
Multi-threading flash access is not supported by
flash_write_protection_set().
flash_write_protection_set() will be deprecated

This fixes the logic in erase_sector() for clearing the previous
sector number. The logic was reversed, clearing bits it should not
clear and keeping previous bits of the sector number. In practice this
does not seem to have had any effect on the current functionality, but
it will start to matter later if e.g. flash interrupts are enabled.

Convert from device_get_binding to DEVICE_DT_GET. In doing this we
no longer need the label in the devicetree node so we remove that.
Removed all __ASSERT_NO_MSG(clk) since we'll get a build error if
DEVICE_DT_GET cant be satisfied, and the clock control api's will
handle reporting if the device_is_ready.

Some format strings were causing warnings.
As elsewhere in this file, offset is type-casted (or not,
depending on compiler) to long int, and then %ld is used in
format string.

When flash is Dualbank and flash size is lower than 512K,
then there is a discontinuity between bank1 and bank2.
Also take into account bank swap capability.

Flash controller support is not yet ready on M4 core.
Remove the chosen declaration to make it clear.
Additionally, generate a build error if this driver is compiled
on M4 core.

Fixes#29831: Implements flash driver for stm32h7 devices.
The driver is independant from the other stm32 families (flash_stm32.c),
only the header interface is (mainly) common.
