[RFC PATCHv2 5/9] drm/tidss: Add dispc7 for DSS7 support

[Tomi Valkeinen <tomi.valkeinen@ti.com>]

From: Jyri Sarha <jsarha@ti.com>

This patch adds support for DSS7 to tidss driver. The DSS7 is a new
DSS version found Texas Instruments Keystone AM65x SoC. DSS7 has many
similarities to DSS6, but it is different enough to warrant a separate
backend driver to keep the code simpler.

The DSS7 on AM65x SoC has two video ports and two video pipeline
(planes). Only one of the them - called VID - supports scaling, the
other is called a VIDL (video lite pipeline). In addition to
traditional MIPI DPI output AM65x supports OpenLDI video output.
