Subject: [PATCH 3/8] efi: modify EFI stub code for arm/arm64

Original EFI stub code parses command line, using old configs: CMDLINE,
CMDLINE_EXTEND and CMDLINE_FORCE. New generic builtin command line use
new configs: CMDLINE_PREPEND, CMDLINE_APPEND and CMDLINE_OVERRIDE, which
depend on CMDLINE_BOOL.
