So fare all nRF flash memories had flash base address at 0.
nRF flash driver was implemented in such way that it
really used absolute addresses, while convention are relative
addresses (for flash_map as well), which was not visible as start
address offset was 0.
It will become visible on nRF53 which has networking flash
with non-zero base address.
This patch switch nRF flash driver to use relative addresses for flash.
UICR absolute addressing is kept.

The smallest region that can be erashed is one sector, so setting
SPI_NOR_FLASH_LAYOUT_PAGE_SIZE=2048 will fail at runtime when the
flash page API is used to erase a single (or misaligned) page. Add a

Add internal API to enter and exit deep power-down mode. Add Kconfig
option to return to DPD whenever device is not active.
When device power management becomes more mature it should be possible
to implement it, which would allow use of DPD without having to enter

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.
Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.
[*] Enable foo ---
This is how it would be shown if there were children but they all
happened to be invisible as well.
With a regular 'config', it turns into
[*] Enable foo
Change all pointless 'menuconfig's to 'config's.
See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

These calls are not accessible in CI test, nor do they get built on
common platforms (in at least one case I found a typo which proved the
code was truly unused). These changes are blind, so live in a
separate commit. But the nature of the port is mechanical, all other
syscalls in the system work fine, and any errors should be easily

Variable pages_per_bank has been introduced to ease page erase
in dual bank configurations. This has been implemented using
FLASH_OPTR_DUALBANK definition.
It happen that this was not taking into account L4+ series that
use FLASH_OPTR_DBANK instead of FLASH_OPTR_DUALBANK. This lead
to compilation issue for this driver in case of L4+ series.
So, this patch is adding the support of FLASH_OPTR_DBANK definition.
Besides, FLASH_OPTR_DUALBANK (as FLASH_OPTR_DBANK) are actually
defining availability of an option byte to configure use of Dual
Bank. So besides of its definition, its value in flash OPTR register
should be checked to ensure Dual Bank configuration is used.
This patch is taking this into account by adding the check of this
byte. Error -ENOTSUP is returned in case Single Bank is configured
since it has not be validated yet (in case Dual Bank is possible but
not configured).
