drm: tiny: Add support for Mayqueen Pixpaper e-ink panel 



Introduce a DRM driver for the Mayqueen Pixpaper e-ink display panel,
which is controlled via SPI. The driver supports a 122x250 resolution
display with XRGB8888 format.

Also, add a MAINTAINERS entry for the Pixpaper driver.

	  DRM driver for the Mayqueen Pixpaper e-ink display panel.



















	  This driver supports small e-paper displays connected over SPI,









	  with a resolution of 122x250 and XRGB8888 framebuffer format.









	  It is intended for low-power embedded applications.



















	  If M is selected, the module will be built as pixpaper.ko.
