The goal of this series is to get the built-in LCD of the LEGO MINDSTORMS EV3
working.

v2 changes:
* Wrote a new driver for ST7586 instead of combining it with existing drivers
* Don't touch MIPI DBI code (other than the patch suggested by Noralf)
* New defconfig patch

v3 changes:
* New patch to generalize tinydrm_xrgb8888_to_gray8() so that it can be reused.
* Device tree bindings in separate patch.
* Fixed incorrect device tree binding pin descriptions.
* Added MAINTAINERS entry for drivers/gpu/drm/tinydrm/st7586.c.
* Removed "mipi_dbi_" from function names in st7586.c.
* Moved init and fini to pipe_enable and pipe_disable ops.
* Dropped RGB565 format.
* Made adjustments for the fact the controller cannot be read via SPI.
* Dropped st7586.h - values moved into st7586.c.
