For the flash driver, the base address is the MCU internal flash
address (usually 0x8000000). This PR gets the that address
from the device tree node "st,stm32-nv-flash"
instead of relying on the CONFIG_FLASH_BASE_ADDRESS
which might differ when building for another flash memory.

STM32U5X has 128k/256k/512k/1M/2M dual bank Flash.
The address of the 2 bank are continuous, so it's no need a "Dummy page"
in "stm32_flash_layout", which cause wrong slot1 section (for secondary
image), and the BANK2_OFFSET is not right either, which cause
"flash_stm32_valid_range" return a failure.
To fix the issue, just set CONFIG_FLASH_SIZE to STM32_SERIES_MAX_FLASH
Tested on NUCLEO-U545RE with mcuboot.

STM32L5 have a write block size of 8, but STM32U5 and STM32H5 have a
write block size of 16. Convert write_dword() and
flash_stm32_write_range() to write write-block-size data at a time.

STM32L5 have a write block size of 8, but STM32U5 and STM32H5 have a
write block size of 16. Use write-block-size from the device tree
instead of hardcoding this value when validating the range of write
operations.

Introduce the stm32h5 serie to the the existing flash driver
It is based on the stm32l5 model.
Add a function to check if the flash is in dual
or single bank mode.
Some stm32 devices can map 2 or 1 flash banks.
Adapt the FLASH register names for the stm32h5 mcu.

Requesting page layout triggers filling bank array
only once, and returns pre-filled array on consequential calls.
But ignores array size.
Remember size of this array as well.

Adjust the size of the stm32_flash_layout[] table depending on the
bank configuration of the stm32u5 or stm32l5 devices.
That will avoid div by zero error in flash_get_page_info()
if the layout_size is not correct.
Assign the *layout_size only once with the correct value : 3 or 1.

Adds the stm32u5 flash controller driver for this serie
to the existing stm32l5 flash driver part
Only 1 or 2 MB devices exist today (4MB is possible in the future).
This flash controller driver is adapted from the flash_stm32l5.c

STM32L5 has option to disable dual bank support.
When this is disabled, the flash page size is changed
from 2k pages to 4k pages. This PR adds support for this
diversity.

This commit adds flash driver in non-secure mode for stm32l5x
series with icache enabled. This commit also adds a flash
programming error status check applicable for all platforms
except stm32f1 series.
