When printing the contents of an size_t variable we need to use z prefix
to the format character in order to get the correct format type
depending on 32 or 64bit-ness.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

A large number of files include <flash.h> as it used to be how various
SPI flash related functions were found, or for other reasons entirely.
In order to migrate some further CONFIG symbols to Kconfig we need to
not include flash.h in cases where we don't have a NOR flash of some
sort enabled. Furthermore, in cases where we are in common code and it
doesn't make sense to try and further refactor the code itself in to new
files we need to guard this inclusion.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Now, we have spi_write_then_read routine that would handle
spi_xfer handling based on the tx_buf and rx_buf parameters.
So, replace individual flash read/write/cmd transfer call
with spi_write_then_read.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Flash id detection should be the first step to enumerate
the connected flash on the board, once ie done checking
with respective id codes locally in the driver all this
should be part of jedec_probe instead of id detection and
validated through flash_info{} table separatly.

Atmel DataFlash chips have commands different from common spi
flash commands.
Atmel DataFlash also have special page-size.
This driver add support for accessing Atmel DataFlash.
It is based on the Driver Model.
Example:
=> sf probe 1:0
SPI DataFlash: Detected AT45DB021B with page size 264 Bytes, erase size 264 Bytes, total 264 KiB, revision d
=> sf erase 0 42000
SF: 270336 bytes @ 0x0 Erased: OK
=> mw.l 82000000 45444342 20000
=> sf write 82000000 0 42000
SF: 270336 bytes @ 0x0 Written: OK
=> sf read 83000000 0 42000
SF: 270336 bytes @ 0x0 Read: OK
=> cmp.b 82000000 83000000 42000
Total of 270336 byte(s) were the same
