soc/mediatek: Prevent passing NULL MIPI commands

Previously (before CB:56965) mtk_dsi_send_init_command() would ignore
NULL initialization commands passed to it. However, in the current code
mipi_panel_parse_init_commands() doesn't check that (see CB:57150), so
we should check it on the caller side from mtk_dsi_init().
