KVM: arm64: vgic-its: Fix compatibility with 32-bit
Evaluate GITS_BASER_ENTRY_SIZE once as an int data (GITS_BASER<n>'s
Entry Size is 5-bit wide only), so when used as divider no reference
to __aeabi_uldivmod is generated when build for AArch32.
Use unsigned long long for GITS_BASER_PAGE_SIZE_* since they are
used in conjunction with 64-bit data.
