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.

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.
