[PATCH 17/21] arm64: dts: allwinner: h616: add ACx00 EPHY resources

Expose logical SID cells for the AC200/AC300 EPHY calibration, the combined
companion-variant and AC300-calibration-range configuration, and the AC200
bandgap fields.

Also describe the PA10/PA11 I2C3 pin group used by the AC200 control
interface.
