soc/mediatek: Prevent passing NULL MIPI commands

Previously (before CB:56965 [1]) 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 [2]), so we should check it on the caller side from
mtk_dsi_init().

[1] b2a1480191 device: Move MIPI panel library from
               mainboard/google/kukui into common
[2] 4757a7ea33 mipi: Make panel init callback work directly on DSI
               transaction types
