Variables that are input (IN) variables to EFI functions should be
marked as const. Just avoid potential problems of changing data that
shouldn't be changed.

So I find myself constantly doing something similar to this when
troubleshooting EFI because I like to put print statements to see data
and figure out where problems are. The EFI print functions all take const
data but much of the data is not marked as const. If you don't like this
that's fine but I was looking at the 3 different EFI branches I have locally
and this change is in all 3 in one shape or another.
