nb/intel/sandybridge/gma.c: Remove useless if condition
There's a useless check with both branches doing the same: enabling RC6
and disabling RC6p. In past, this condition would enable RC6p in IVB but
not on SNB. Then, at some point, RC6p was considered unstable and was
disabled, but the condition remained.
It's not needed so let's remove it.
