Wenyou Yang e4677f1ae2 arm: at91/spl: atmel_sfr: move saic redirect to separate file
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.
