The lmb_map_update_notify() function is used to update the EFI memory
map based on corresponding changes in the LMB map. This is causing
build failure with a certain old architecture(armv5) toolchain, when
building with CONFIG_CC_OPTIMIZE_FOR_DEBUG symbol on platforms which
do not enable the EFI_LOADER code. Build the code in
lmb_map_update_notify() only when the EFI_LOADER config is enabled to
get around this issue.
