efi: Simplify arch_efi_call_virt() macro 

ANBZ: #5200

commit 8add9a3a22 upstream.

Currently, the arch_efi_call_virt() assumes all users of it will have
defined a type 'efi_##f##_t' to make use of it.

Simplify the arch_efi_call_virt() macro by eliminating the explicit
need for efi_##f##_t type for every user of this macro.
