We want to be able to set TCON TOP muxes at runtime. Add helpers for
that.
Old, static configuration of muxes at probe time is preserved for now.
It will be removed when R40 TCON starts using them.

As already described in DT binding, TCON TOP is responsible for
configuring display pipeline. In this initial driver focus is on HDMI
pipeline, so TVE and LCD configuration is not implemented.
Implemented features:
- HDMI source selection
- clock driver (TCON and DSI gating)
- connecting mixers and TCONS
Something similar also existed in previous SoCs, except that it was part
of first TCON.
