clk: sunxi-ng: Add A80 CCU

Add support for the main clock unit found in the A80. Some clocks were not documented in the released user manual, but were found in the official kernel from Allwinner. These include controls for the I2S, SPDIF, SATA, and eDP blocks. Note that on the A80, some subsystems have separate clock controllers downstream of the main clock unit. These include the MMC, USB, and display engine subsystems.
