From Lahaina onwards, for compressed DSI output, widebus should be enabled.
In widebus mode, 6 bytes of data are transmitted per pclk.
For uncompressed output, widebus must be disabled to transmit 3 bytes
of uncompressed data per pclk.

For command mode panels, if a dynamic mode switch occurs on
the first frame, the current code skips DSI controller initialization
and registering for error handlers. This causes the software state
to be uninitialized for DSI CTRL, resulting in command transfer
failures and eventual crash. The change ensures that initialization
is complete even if the DMS occurs on first frame.
