KVM: arm/arm64: Fix idmap size and alignment
Although the idmap section of KVM can only be at most 4kB and must be aligned on a 4kB boundary, the rest of the code expects it to be page aligned. Things get messy when tearing down the HYP page tables when PAGE_SIZE is 64K, and the idmap section isn't 64K aligned. Let's fix this by computing aligned boundaries that the HYP code will use.
