[OE-core] [PATCH 5/5] bootimg: Allow for EFI-only boot images

From: Darren Hart <dvhart at linux.intel.com>
Condition building PCBIOS legacy images on MACHINE_FEATURES containing "pcbios"
or not containing "efi". This ensures existing BSPs will continue to get the
old PCBIOS legacy-only images. New BSPs can add "efi", "pcbios", or both. The
images created likewise support one or the other or both.
EFI-only ISO images are untested.
