u-boot-internal.inc: Do not check the SHA validation for branch

[floion]

Specifying the branch name and having the tag set as SRCREV makes bitbake error out:

WARNING: u-boot-edison-v2017.03-r0 do_fetch: Failed to fetch URL git://github.com/andy-shev/u-boot.git;branch=edison;protocol=https, attempting MIRRORS if available ERROR: u-boot-edison-v2017.03-r0 do_fetch: Fetcher failure: Unable to find revision 506270615cf8e567b0b153bd5c2de47c35f671f8 in branch edison even from upstream ERROR: u-boot-edison-v2017.03-r0 do_fetch: Fetcher failure for URL: 'git://github.com/andy-shev/u-boot.git;branch=edison;protocol=https'.

From http://git.yoctoproject.org/cgit.cgi/poky/plain/bitbake/lib/bb/fetch2/git.py:

• nobranch Don't check the SHA validation for branch. set this option for the recipe referring to commit which is valid in tag instead of branch. The default is "0", set nobranch=1 if needed.

Hi @htot I guess this also needs to go to master if code review is okay

Yeah, without it u-boot was hanged when booting. Will have a follow up PR with some more changes early next week.
