Subject: [PATCH 1/2] dt-bindings: reset: thead,th1520-reset: add more VOSYS resets

VOSYS contains more resets for a display pipeline, includes ones for the
display controller (called DPU in the manual), the HDMI controller and 2
MIPI DSI controllers.

Allocate IDs for these resets in the dt binding header file.

Now all peripheral related VOSYS reset controls are here, only the bus
matrix / IOPMP ones are missing, which shouldn't be messed with.
