Marc Zyngier af20814ee9 ARM: KVM: add world-switch for AMAIR{0,1}
HCR.TVM traps (among other things) accesses to AMAIR0 and AMAIR1.
In order to minimise the amount of surprise a guest could generate by
trying to access these registers with caches off, add them to the
list of registers we switch/handle.
