Can we get this two small patches merged? They fix a regression although it worked previously just accidentally. The only drivers using DM_FLAG_VITAL are clk-rcar-gen3.c, rzg2l-cpg.c and apple_dart.c all used on arm SoCs. arch/arm/lib/bootm.c already uses a device_remove call with DM_REMOVE_NON_VITAL so adding it to efi_loader looks reasonable as regression fix.
