efi_loader: fix building crt0 on arm
Before the patch an undefined constant EFI_SUBSYSTEM was used in the
crt0 code. The current version of binutils does not swallow the error.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403
The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already
defined in pe.h. So let's factor out asm-generic/pe.h for the
image subsystem constants and use it in our assembler code.
IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification
let's use IMAGE_SUBSYSTEM_EFI_ROM instead.
The include pe.h is only used in code maintained by Alex so let him be the
maintainer here too.
