The RPC HF might be locked by ATF, and any access to its register
space would result in complete hang. Disable the RPC HF by default.
The ATF should be patched to set RPC node status = "okay" in the DT
fragment it passes to U-Boot in case the RPC HF access is unlocked,
and that way U-Boot could access the RPC HF safely.

Enable the RPC Hyperflash driver on R8A7795,R8A7796,R8A77965
Salvator-X,ULCB and R8A77990 Ebisu. Note that to make the HF
accessible, mainline ATF is mandatory and must be built with
RCAR_RPC_HYPERFLASH_LOCKED=0 . Note that this is intended for
development and testing convenience only and must be disabled
in deployment for platform security reasons.

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.

Pull out u-boot extras into dtsi files to make synchronization of DTS
from Linux kernel as easy as a simple copy. All the U-Boot extras are
now in *-u-boot.dts* files instead.
