KVM: arm64: Split kvm_pgtable_stage2_destroy()
Split kvm_pgtable_stage2_destroy() into two:
- kvm_pgtable_stage2_destroy_range(), that performs the
page-table walk and free the entries over a range of addresses.
- kvm_pgtable_stage2_destroy_pgd(), that frees the PGD.
This refactoring enables subsequent patches to free large page-tables
in chunks, calling cond_resched() between each chunk, to yield the
CPU as necessary.
Existing callers of kvm_pgtable_stage2_destroy(), that probably cannot
take advantage of this (such as nVMHE), will continue to function as is.
