The page_layout API returns pointers to kernel memory and is not
exposed to user mode. This is fine for flash_get_page_count()
and flash_get_page_info APIs since these copy the values, but some
redesign work will be needed to get flash_page_foreach() working in
user mode since we do not want the callback running in a privileged
state.
Due to the way that (even unimplemented) system call prototypes are
generated, the definition of struct flash_pages_info needed to be
moved outside of the #ifdef.

This path introduce API for retrieving a minimum write-block-size
supported by the flash driver.
This value can differ from the hardware alignment requirement
(as it does for nRF5x).
As the driver has a certain requirement for alignment
when writing, it is necessary to export this value for upper modules
which need to know the write-block-size (for instance, NFFS needs this).

This patch adds a routine which can be used to iterate over all flash
pages on the device.
This can be also done by using flash_get_page_info_by_idx(), but that
would add an unnecessary loop over the layout array for each page.

Added an internal function to obtain the flash page layout in
run-length encoded format. The API is simple and allows the actual
public API implementations to be simple and maintainable.
This feature can be enabled by using the FLASH_PAGE_LAYOUT Kconfig
option. This API is required for the implementation of flash file
system.
Added a public API to get flash page information (size and start offset)
by offset within the flash and by index of the page.
Added a generic implementation of the internal flash_get_page_info API.
Added an additional public API call to get the total count of pages in
the flash memory and its generic implementation.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

This patch replaces all occurences of the macro DEV_OK by the actual
value 0 at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

Now that the internal libc has the off_t type it's the natural choice
for the offset parameters in the flash API.

This makes the ordering consistent e.g. with SPI, Bluetooth and
Networking APIs. This also follows the order of parameters in the
POSIX read/write APIs.

size_t is the natural type for any integer that describes a number of
bytes. For the actual data use void pointers to avoid callers having
to do explicit typecasts if the data doesn't originate in a uint8_t
array. Also use a const pointer for writing to avoid typecasts for
data that originates in a const location.
