arm/arm64: KVM: Fix hyp mappings of vmalloc regions
Using virt_to_phys on percpu mappings is horribly wrong as it may be backed by vmalloc. Introduce kvm_kaddr_to_phys which translates both types of valid kernel addresses to the corresponding physical address. At the same time resolves a typing issue where we were storing the physical address as a 32 bit unsigned long (on arm), truncating the physical address for addresses above the 4GB limit. This caused breakage on Keystone.
