drm/bridge: tc358767: Add DSI-to-(e)DP mode support

Browse source

Implement DSI-to-e(DP) mode, which is a mix of currently supported
DSI-to-DPI and DPI-to-(e)DP modes. The input side is configured as
either DSI or DPI, the DP AUX channel is registered for both input
side options, and the DSI host is attached for both DPI and (e)DP
output side options.

One notable detail is that the DSI-to-(e)DP mode requires the Pixel
PLL to be always enabled, which is not needed for DPI-to-(e)DP mode
which gets the matching clock direct from DPI Pixel Clock instead.
