drm/tinydrm: Move mipi-dbi 

This moves mipi-dbi to be a core helper with the name drm_mipi_dbi.

Fixup include's in drivers.
Move the docs entry and delete tinydrm.rst.
Delete the last tinydrm todo entry.

v2: Make DRM_MIPI_DBI tristate to enable it being built as a module.

Driver Specific
===============
tinydrm
-------
Tinydrm is the helper driver for really simple fb drivers. The goal is to make
those drivers as simple as possible, so lots of room for refactoring:
- extract the mipi-dbi helper (well, the non-tinydrm specific parts at
least) into a separate helper, like we have for mipi-dsi already. Or follow
one of the ideas for having a shared dsi/dbi helper, abstracting away the
transport details more.
