ARM: shmobile: Initial r8a73a4 SoC support V3
V3 of initial support for the r8a73a4 SoC including: - Single Cortex-A15 CPU Core - GIC - Architecture timer No static virtual mappings are used, all the components make use of ioremap(). DT_MACHINE_START is still wrapped in CONFIG_USE_OF to match other mach-shmobile code. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
