ARM: KVM: get rid of S2_PGD_SIZE
S2_PGD_SIZE defines the number of pages used by a stage-2 PGD and is unused, except for a VM_BUG_ON check that missuses the define. As the check is very unlikely to ever triggered except in circumstances where KVM is the least of our worries, just kill both the define and the VM_BUG_ON check.
