The SAMA5D2 has a second internal SRAM that can be reassigned as a L2
cache memory.
Make sure it is configured as a L2 cache memory when booting from a SPL
image.
Based on the commit b5ea95ef2b5b from the at91bootstrap repository.

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.
