83d290c56f 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.

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

997399fa42 powerpc: Fix CamelCase checkpatch warnings
85xx, 86xx PowerPC folders have code variables with CamelCase naming conventions.
because of this code checkpatch script generates "WARNING: Avoid CamelCase".

Convert variables name to normal naming convention and modify board, driver
files with updated the new structure.

d3504fee73 spi: Use spi_alloc_slave() in each SPI driver
Rather than each driver having its own way to allocate a SPI slave,
use the new allocation function everywhere. This will make it easier
to extend the interface without breaking drivers.

9905757e29 powerpc/espi: remove write command length check
Current espi controller driver assumes the command length of write command is
not equal to '1', it was made based on SPANSION SPI flash, but some SPI flash
driver such as SST does use write command length as '1', so write command on
SST SPI flash will not work. And the length check for write command is not
necessary for SPANSION, though it's harmless for SPANSION, it will stop write
operation on flashes like SST, so we remove the check.
