Currently, the arch_efi_call_virt() assumes all users of it will have
defined a type 'efi_##f##_t' to make use of it. It is unnecessarily
forcing the users to create a new typedef when __efi_rt_asm_wrapper()
actually expects void pointer.
Simplify the arch_efi_call_virt() macro by using typeof(p->f) which must
be a pointer as required by __efi_rt_asm_wrapper() and eliminate the
explicit need for efi_##f##_t type for every user of this macro.
This is needed now in preparation to enable PRMT support on ARM64.
