Without this delay, the panel could received a frame early & generate a crash of panel (black screen).

This also fixes some mode check and irq timeout issue in MTK dsi code. Since some dsi code (e.g. mtk_dsi) have following call trace: 1. drm_panel_disable(), which calls innolux_panel_disable() 2. switch to cmd mode 3. drm_panel_unprepare(), which calls innolux_panel_unprepare() However, mtk_dsi needs to be in cmd mode to be able to send commands (e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()), so we need these functions to be called after the switch to cmd mode happens, i.e. in innolux_panel_unprepare.
