u-boot: support merging .cfg files for UBOOT_CONFIG
U-boot recipe supports .cfg files in SRC_URI, but they would be merged
to .config during do_configure only when UBOOT_MACHINE is set, we
should also support merging .cfg files for UBOOT_CONFIG.
The intension of
4fde8c8 looks more than append delta-config snippets to
u-boot config and should probably be rewritten to express that much better
than implicitely assume all "*.cfg" are for merging into .config.
