dt-bindings: add device tree binding for Allwinner H6 main CCU

Browse Source 
[ Upstream commit 2e08e4d2ff488424919d69dd211ac860a019ac1d ]

The Allwinner H6 main CCU uses the internal oscillator of the SoC, which
is different with old SoCs' main CCU.

Add device tree binding for the Allwinner H6 main CCU.

For the main CCU on H6, one more clock is needed:
- "iosc": the SoC's internal frequency oscillator
For the PRCM CCUs on A83T/H3/A64, two more clocks are needed:
- "pll-periph": the SoC's peripheral PLL from the main CCU
- "iosc": the SoC's internal frequency oscillator
