[PULL 43/50] ARM: Introduce MPIDR_LEVEL_SHIFT macro

[Christoffer Dall]

From: Vladimir Murzin <vladimir.murzin at arm.com>

vgic-v3 driver uses architecture specific MPIDR_LEVEL_SHIFT macro to
encode the affinity in a form compatible with ICC_SGI* registers.
Unfortunately, that macro is missing on ARM, so let's add it.
