kernel-yocto: set master branch to a defined SRCREV
To support custom repositories that set a SRCREV and that only have
a single master branch, do_validate_branches needs a special case
for 'master'. We can't delete and recreate the branch, since you
cannot delete the current branch, instead we must reset the branch
to the proper SRCREV.
