Align with cmd_sf, and try to rely on DT for spi speed and mode,
and still fallback on spi_flash_probe() if it fails.

With the current scheme, spi_flash_probe() will be called
with CONFIG_SF_DEFAULT_SPEED and CONFIG_SF_DEFAULT_MODE
with are set to 0 by default on DT platforms using DM_SPI_FLASH.

Like cmd_sf, keep the option to specify the speed and mode
from the dfu_alt_mode string, but rely on DT properties
if not specified.

Using CONFIG_SF_DEFAULT_SPEED and CONFIG_SF_DEFAULT_MODE
makes the SPIFC controller on Amlogic Meson G12B & SM1
hardware fail and is unable to recover until a system reboot.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

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.

Remove <common.h> from this driver directory and when needed
add missing include files directly.

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.

When parsing the dfu_alt_info, check the number of arguments
and argument string strictly. If there is any garbage data
(which is not able to be parsed correctly) in dfu_alt_info,
that means something wrong and user may make a typo or mis-
understanding about the syntax. Since the dfu_alt_info is
used for updating the firmware, this mistake may lead to
brick the hardware.
Thus it should be checked strictly for making sure there
is no mistake.

If dfu_alt_info has repeated spaces or tab (for indentation or
readability), the dfu fails to parse it. For example, if
dfu_alt_info="mtd nor1=image raw  100000 200000" (double spaces
after "raw"), the image entity start address is '0' and the size
'0x100000'. This is because the repeated space is not skipped.

Use space and tab as a separater and apply skip_spaces() to
skip redundant spaces and tabs.

Not all SPI flashes and controllers can do continuous transfer longer
than 16 MiB, so perform the DFU read in 16 MiB chunks.

It is a pain to have to specify the value 10 in each call. Add a new
