[PATCH 19/21] arm64: dts: allwinner: h6: add AC200 EPHY resources

Add the H6 I2C3 controller and pinmux, the PWM-derived 24 MHz AC200
clock, SID calibration cells, RMII pinmux, and the AC200 MFD and EPHY
control nodes.

Describe the co-packaged AC200 INTB output on PB20. Keep both reusable
AC200 nodes disabled so boards must explicitly enable the parent and its
EPHY control function when the companion is present.
