[PATCH] drm/panel: ronbo-rb070d30: Use mipi_dsi_*_multi() functions

[Hsieh Hung-En]

Replace the deprecated mipi_dsi_dcs_exit_sleep_mode() and
mipi_dsi_dcs_enter_sleep_mode() calls in the enable and disable callbacks
with their _multi variants, as suggested in Documentation/gpu/todo.rst.

The callbacks retain the same return values. The new helpers additionally
log an error if the command fails.

Notes:
    Compile-tested on arm64 with W=1; not tested on hardware.
