Use new nrfx hal function to memcpy from flash
instead of accessing the array directly.
That function is inlining a memcpy for real targets,
so there is no practical difference for those.

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.

Rework ticker synchronization using newly introduced

In kconfig synchronization using ll ticker become choice
option.
If CONFIG_SOC_FLASH_NRF_PARTIAL_ERASE is enabled the erase

Previously interval was always ~90 ms, which looks like it was kept
so disproportional by oversight while the partial erase was

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

When enabled, instead of erasing entire flash page at once, page will
be erased in defined time slices. Erasing single page stalls CPU
for significant time share (~80ms) and partial erase divides the
operation in to the shorter time periods, resuming CPU operation in
meantime and enabling better scheduling of time sensitive operations.

There is timeout guard, in form of k_sem_get within work_in_time_slice,
used to detect if flash operation takes longer than expected maximum
and to return error code in such case. The processing of this timeout
is missing cancellation of scheduled ticker job that would attempt to
perform another operation. This causes problem as context for ticker
is created, on stack, within erase/write_in_timeslice which
would conclude when timeout occurs, folding the stack in process.

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.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c
