drm/i915: restore pipeconf regs unconditionally
On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume. So restore them unconditionally along with actually restoring pipe B's palette correctly. Signed-off-by: Dave Airlie <airlied@redhat.com>
