configurations, not using the mpddrc register map structure,
struct atmel_mpddrc, in order to increase readability and reduce

To make saic redirect code sharing with other SoCs, move the
saic redirect code from SAMA5D4 particular file,
mach-at91/armv7/sama5d4_devices.c to a separate file,
mach-at91/atmel_sfr.c
Move ATMEL_SFR_AICREDIR_KEY definition to sama5d4.h, because each
SoC has its own value.

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one. This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

Some peripherals may need a second clock source that may be different
from the system clock. This second clock is the generated clock (GCK)
and is managed by the PMC via PMC_PCR.
For simplicity, the clock source of the GCK is fixed to PLLA_CLK.
