[PATCH v2 05/24] 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_ELx_SET.

Initialize MAIR_EL2 to MAIR_ELx_SET 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.
