staging: sm750fb: change definition of CRT_DISPLAY_CTRL multi-bit fields
Use more straight-forward definitions for multi-bit fields of CRT_DISPLAY_CTRL register and use open-coded implementation for register manipulation Signed-off-by: Mike Rapoport <mike.rapoport@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
