[PATCH v3 25/25] arm64: dts: allwinner: a64-amarula-relic: Enable Techstar TS8550B MIPI-DSI panel

Amarula A64-Relic board by default bound with Techstar TS8550B MIPI-DSI panel, add support for it.

DSI panel connected via board DSI port with, - DC1SW as AVDD supply - DCDC2 as DVDD supply - DCDC1 as VCC-DSI supply - PD24 gpio for reset pin - PD23 gpio for backlight enable pin
