Subject: [PATCH v6 1/7] dt-bindings: display: panel: Add himax hx83102 panel bindings

In V1, discussed with Doug and Linus [1], we need break out as separate
driver for the himax83102-j02 controller. Beacuse "starry,himax83102-j02"
and in this series "BOE nv110wum-l60" "IVO t109nw41" panels use same
controller, they have some common CMDS. So add new documentation for
this panels.

For himax83102-j02 controller, no need 3v3 supply, so remove it.
