drm/bridge: tc358775: Add support for tc358765

The tc358775 bridge is pin compatible with earlier tc358765 according to
the tc358774xbg_datasheet_en_20190118.pdf documentation. Compared to the
tc358765, the tc358775 supports a STBY GPIO and higher data rates.

The tc358765 has a register bit for video event mode vs video pulse mode.
We must set it to video event mode for the LCD output to work, and on the
tc358775, this bit no longer exists.

Looks like the registers seem to match otherwise based on a quick glance
comparing the defines to the earlier Android kernel tc358765 driver.
