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.

Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards.
Note that according to errata from Atmel, OHCI is not operational
on the first revision of at91sam9g45 chip. So this patch enables
OHCI support for later revisions.

This patch is part of migrating the AT91 support towards
using C struct for all SOC access.
It removes one more CONFIG_AT91_LEGACY warning.
at91_pmc.h needs cleanup after migration of the drivers
has been done.

This patch corrects the missing PLLB initialization in usb_cpu_init()
for AT91SAM9261.
Because of the missing PLLB initialization, the USB support for all
AT91SAM9261 based boards will work only if the PLLB is configured by a
precedent bootloader.
