Changes since first version of the series:
- Move tilcdc_regs.h changes from "drm/tilcdc: Enable palette loading
for revision 2 LCDC too" to "drm/tilcdc: Add tilcdc_write_mask() to

These patches are inspired by this series form Bartosz Golaszewski:
https://www.spinics.net/lists/arm-kernel/msg539629.html
The patches are based on drm-next plus the earlier patches that I plan
to send in a pull request for 4.10. The base + these patches are
pushed here:
