Subject: [PATCH 0/3] A64/H3/H6 R_CCU clock fixes

Hi all,

I was examining the H6 BSP clock driver[1] for guidance when porting an
AR100 firmware[2] to the H6 SoC. I found some inconsistencies between
that code and the sunxi-ng driver.

I don't have a good way to verify the first patch. Someone with an
oscilloscope could set the divider and check the I2C/RSB frequency.

Patch 2 should have no functional change.

Patch 3 was verified by benchmarking. Details are in the commit message.
