GFX-Display: enabled Enzo MIPI panel with video mode.

BZ: 20132

1. Also included Enzo panel's command mode codes.
2. Fixed the "Android" splash hang issue in command mode, because when
   updating DBI panel, it shouldn't clean the IN_DSR flag if FB is
   damaged, as the flag will be cleaned when entering DSR.
3. Fixed the Enzo panel power on unstability issue in command mode,
   by not setting DSI PLL in mdfld_auo_dsi_dbi_power_on(), as it has
   been set in mdfld_dsi_controller_dbi_init().
