Feiyang FY07024DI26A30-D MIPI_DSI panel is desiged to attach with
DSI connector on pine64 boards, enable the same for pine64 LTS.

DSI panel connected via board DSI port with,
- DC1SW as AVDD supply
- DLDO2 as DVDD supply
- DLDO1 as VCC-DSI supply
- PD24 gpio for reset pin
- PH10 gpio for backlight enable pin
