[PATCH v1 04/24] kvm: arm64: Initialize MAIR_EL2 using a constant

[David Brazdil]

MAIR_EL2 is currently initialized to the value of MAIR_EL1, which itself
is set to a constant MAIR_EL1_SET.

Initialize MAIR_EL2 to the MAIR_EL1_SET constant directly in preparation
of allowing KVM to start CPU cores itself and not initializing itself
before ERETing to EL1. In that case, MAIR_EL2 will be initialized before
MAIR_EL1.
