arm64: dts: qcom: sdm845-oneplus: Update compatbible and add DDIC supplies

Browse Source 
Update the compatible to reflect combination of DDIC and panel.

Original compatible describing only the DDIC used, but omit describing
the panel used (Samsung AMS641RW), which we have no way to detect.

There are two additional supplies used by the panel, both are GPIO
controlled and are left enabled by the bootloader for continuous splash.

Previously these were (incorrectly) modelled as pinctrl. Describe them
properly so that the panel can control them.
