From: Icenowy Zheng <icenowy@xxxxxxxx>
Now we have driver for the PRCM CCU, switch to use it instead of
old-style clock nodes for apb0-related clocks in sunxi-h3-h5.dtsi .
The mux 3 of R_CCU is still the internal oscillator, which is said to be
16MHz plus minus 30%, and get a measured value of 15MHz~16MHz on my two
H3 boards and one H5 board.

Changes in v3:
- Change osc32000 to iosc.
