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.

mtd: nand: Rename nand.h into rawnand.h
We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

AT91 RSTC registers are battery-backuped, so their values
are not reset across power cycles. One of those registers,
the AT91_RSTC_MR register, is being modified by U-Boot, in
the ethernet initialisation routine, to generate a 500ms
user reset.
Unfortunately, this value is not being restored afterwards,
causing subsequent resets to also last for 500ms.
This long reset sequence causes problems (at least) in the
boot sequence from NOR: by the time the CPU tries to load
a program from the NOR flash, the latter is still in reset
and not yet available.
Additionaly, this patch fixes a bug in the original code which
caused the reset delay to last for 2s instead of 500ms.
