Use functions introduced in commit 966e397e4f60 ("drm/mipi-dsi:
Introduce mipi_dsi_*_write_seq_multi()") and commit f79d6d28d8fe
("drm/mipi-dsi: wrap more functions for streamline handling") for 
sitronix-st7703 based panels.

Why no return early here in the error case (same for the other cases
below) giving us an indication which step went wrong?

Would be nice to keep the debug message.

Similar to the above: it'd be nice to keep the information which step
failed.

Return early is hidden in the wrapped *_multi() function calls.

That's done by the _multi() wrappers.

The debug message is still there. Except now it runs only if no errors
have occurred to preserve the previous behavior, where the line 
wouldn't have run in the case of an early return.

The difference between the new multi variants of the functions and the 
old functions is that multi functions don't run if an error has 
occurred previously (thus removing need for early returns), and they 
call dev_err internally in the case of an error, thus letting us know 
where the error occurred without explicitly having to do error handling 
in the call site.
