 drm/bridge: tc358768: Attempt to fix DSI horizontal timings 
The DSI horizontal timing calculations done by the driver seem to often
lead to underflows or overflows, depending on the videomode.

There are two main things the current driver doesn't seem to get right:
DSI HSW and HFP, and VSDly. However, even following Toshiba's
documentation it seems we don't always get a working display.

This patch attempts to fix the horizontal timings for DSI event mode, and
on a system with a DSI->HDMI encoder, a lot of standard HDMI modes now
seem to work. The work relies on Toshiba's documentation, but also quite
a bit on empirical testing.

This also adds timing related debug prints to make it easier to improve
on this later.

The DSI pulse mode has only been tested with a fixed-resolution panel,
which limits the testing of different modes on DSI pulse mode. However,
as the VSDly calculation also affects pulse mode, so this might cause a
regression.
