mtd: spi: Add lightweight SPI flash stack for SPL

Add a tiny SPI flash stack that just supports reading data/images from
SPI flash. This is useful for boards that have SPL size constraints and
would need to use SPI flash framework just to read images/data from
flash. There is approximately 1.5 to 2KB savings with this.

SPDX: Convert all of our single license tags to Linux Kernel style

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.

Revert "sf: Fix quad bit set for micron devices"

This reverts commit c56ae7519f141523ba1248b22b5b5169b21772fe.

Once the 'Quad Enable' bit is cleared in their Enhanced Volatile
Configuration Register (EVCR), Micron memories expect ALL commands to use
the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer
accepted.

Within the reverted commit, the write_evcr() function is implemented using
the spi_flash_write_common(), which is a shortcut for the
[ spi_flash_cmd_write_enable(), spi_flash_cmd_write(),
spi_flash_cmd_wait_ready() ] sequence.

Since the internal state of the Micron memory has been changed when the
spi_flash_cmd_write() function completes, the later call of the
spi_flash_cmd_wait_ready() function fails.

Indeed the SPI controller driver is not aware of the SPI protocol switch.

Further patches will fix the support of Micron QSPI memories.

spi: Remove dual flash options/flags

Dual flash code in spi are usually take the spi controller
to work with dual connected flash devices. Usually these
dual connection operation's are referred to flash controller
protocol rather with spi controller protocol, these are still
present in flash side for the usage of spi-nor controllers.

So, this patch remove the dual_flash options or flags in sf
which are triggered from spi controller side.

sf: Remove spansion_s25fss_disable_4KB_erase

In spansion S25FS-S family the physical sectors are grouped as
normal and parameter sectors. Parameter sectors are 4kB in size
with 8 set located at the bottom or top address of a device.
Normal sectors are similar to other flash family with sizes of
64kB or 32 kB.

To erase whole flash using sector erase(D8h or DCh) won't effect
the parameter sectors, so in order to erase these we must use 4K
sector erase commands (20h or 21h) separately.

So better to erase the whole flash using 4K sector erase instead
of detecting these family parts again and do two different erase
operations.

For this:
- Removed spansion_s25fss_disable_4KB_erase code
- Add SECT_4K for S25FS512S chip
