[PATCH v3 04/10] clk: sunxi-ng: add support for Allwinner H5 SoC

[Icenowy Zheng <icenowy-ymACFijhrKM@public.gmane.org>]

Allwinner H5 is a SoC that features a CCU like H3, but with MMC phase
clocks removed (for new MMC controller) and a new bus gate/reset
imported.

Add support for it.

Signed-off-by: Icenowy Zheng <icenowy-ymACFijhrKM@public.gmane.org>
