x86/efi: Move efi_<reserve/free>_boot_services() to arch/x86

efi_<reserve/free>_boot_services() are x86 specific quirks and as such
should be in asm/efi.h, so move them from linux/efi.h. Also, call
efi_free_boot_services() from __efi_enter_virtual_mode() as it is x86
specific call and ideally shouldn't be part of init/main.c
