commit 32c4514455b2b8fde506f8c0962f15c7e4c26f1d upstream.
Wait for the command transmission to be completed in the DSI transfer
function polling for the dc_start bit to go back to idle state after the
transmission is started.
This is documented in the datasheet and failures to do so lead to
commands corruption.
