[mipi_dsi] Add JC8012P4A1-V2 as model

[rayz90]

What does this implement/fix?

Added a JC8012P4A1-V2 model for the MIPI DSI display driver. Some newer units (sold under modelnumber JC8012P4A1 and JC8012P4A1C_I_W_Y) are shipped with a different LCD panel, but still use the same driver chip. I extracted the timings and init sequence from the reference driver.

With the current information, it looks like the devices with a batch number of 2624 or higher have the new LCD panel.
