With this we can eliminate some duplicate code in panel drivers.
Also lgphilips-lb035q02, nec-nl8048hl11-01b, picodlp and
tpo-td043mtea1 gain support of timings control over sysfs.

This elimination makes sense with get_timings(), but having the default
check_timings() and set_timings() linked with the DPI interface doesn't
seem right.
For example, if a panel driver using DSI interface doesn't have it's own
set_timings() op populated, and if some user of DSS call's
set_timings(), it would mess up the DSS2 driver.
Probably having a check like this in check_timings()/set_timings() might
make it safer:
if (dssdev->type = OMAP_DISPAY_TYPE_DPI)
dpi_set_timings(dssdev, timings);
