[meta-intel] [PATCH 0/1][master/dora] Fixup emgd feature merge for fri2

[Darren Hart]

Due to the emgd feature being merged with standard/ltsi and the issue with
do_validate_branches truncating all feature branches to the machine SRC_REV if
it exists in their history, this update is necessary to get EMGD included in the
kernel sources.

Such a fix is also required for crownbay and sys940x. Applies to master and dora
(with a whitespace cleanup).
