cml1: Move find_cfgs() helper to cml1.bbclass
u-boot.inc and busybox.inc contain identical copies of this little
helper. They both inherit the cml1 class and use cml1_do_configure
right after having used this helper, and other recipes that want to
write similar logic for doing Kconfig via fragments will also need it
or something equivalent.
