The hardcoding of the branch (versus a variable) was intentional, since
unlike the kbranch settings it is the same for all BSPs, and it is coupled
to the kernel version.
I vary the repository and branch by overriding the SRC_URI versus
changing it this way (as an example).
That being said, it isn't a terrible idea that it could be modified, it just
isn't something I'd want recipes changing.
If it is something that can be changed, it also needs to have a check that
ensures the kver in the branch matches the kernel being built, otherwise,
it should warn. Much like our kernel version check (variable vs source).
