c71645ad2b arm64 patch: gicv3 support
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>.

1e6ad55c05 armv8/cache: Change cache invalidate and flush function
When SoC first boots up, we should invalidate the cache but not flush it.
We can use the same function for invalid and flush mostly, with a wrapper.

Invalidating large cache can ben slow on emulator, so we postpone doing
so until I-cache is enabled, and before enabling D-cache.

83571bcab1 armv8/cache: Flush D-cache, invalidate I-cache for relocation
If D-cache is enabled, we need to flush it, and invalidate i-cache before
jumping to the new location. This should be done right after relocation.
