This patch add gicv3 support to uboot armv8 platform. Changes for v2: - rename arm/cpu/armv8/gic.S with arm/lib/gic_64.S - move smp_kick_all_cpus() from gic.S to start.S, it would be implementation dependent. - Each core initialize it's own ReDistributor instead of master initializeing all ReDistributors. This is advised by arnab.basu <arnab.basu@freescale.com>. Signed-off-by: David Feng <fenghua@phytium.com.cn>
