ACPI: PRM: Change handler_addr type to void pointer

[ Upstream commit 353efd5e97a7973d78f2634274b57309d0966e29 ]

handler_addr is a virtual address passed to efi_call_virt_pointer.
While x86 currently type cast it into the pointer in it's arch specific
arch_efi_call_virt() implementation, ARM64 is restrictive for right
reasons.

Convert the handler_addr type from u64 to void pointer.
