x86: EFI runtime code mapping enhancement
This patch enhances EFI runtime code memory mapping as following:
- Move __supported_pte_mask & _PAGE_NX checking before invoking
runtime_code_page_mkexec(). This makes it possible for compiler to
eliminate runtime_code_page_mkexec() on machine without NX support.
- Use set_memory_x/nx in early_mapping_set_exec(). This eliminates the
duplicated implementation.
This patch has been tested on Intel x86_64 platform with EFI64/32
firmware.
