drm/ssd130x: Add support for the SSD133x OLED controller family

Browse source

The Solomon SSD133x controllers (such as the SSD1331) are used by RGB dot
matrix OLED panels, add a modesetting pipeline to support the chip family.

The SSD133x controllers support 256 (8-bit) and 65k (16-bit) color depths
but only the 256-color mode (DRM_FORMAT_RGB332) is implemented for now.
