Merge tag 'sunxi-clk-for-4.13' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into clk-next

Pull Allwinner clock patches from Maxime Ripard:

Some new clock units are supported, for the display clocks unsed in the
newer SoCs, and the A83T PRCM.

There is also a bunch of minor fixes for clocks that are not used by
anyone, and reworks needed by drivers that will land in 4.13.
