southbridge/via/vt8237r/ctrl.c: Remove set but unused variable `regm3`
Removing `-Wno-unused-but-set-variable` from `CFLAGS` results in the following error.
CC southbridge/via/vt8237r/ctrl.ramstage.o src/southbridge/via/vt8237r/ctrl.c: In function 'vt8237_cfg': src/southbridge/via/vt8237r/ctrl.c:32:11: error: variable 'regm3' set but not used [-Werror=unused-but-set-variable] cc1: all warnings being treated as errors
There is already a `FIXME` line regarding this issue, added in commit »remove more warnings.« (3c8ac786).
Looking at the history, the file `vt8237_ctrl.c` was based on `k8t890_ctrl.c`, but removed the code needing the variable `regm3` and was not adapted in that place.
Therefore remove the variable `regm3` and use `regm` which should also shadow page E correctly now.
