clk: sunxi-ng: allow set parent clock (PLL_CPUX) for CPUX clock on H3
The CPUX clock, which is the main clock of the ARM core on Allwinner H3, can be adjusted by changing the frequency of the PLL_CPUX clock. Allowing setting parent clock for the CPUX clock, thus the PLL_CPUX clock can be adjusted when adjusting the CPUX clock.
