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.
