[PATCH v3 3/5] clk: sunxi: Add sun9i A80 cpus (cpu special) clock support

From: Maxime Ripard <hidden>

Hi,

The "cpus" clock is the clock for the embedded processor in the A80.
It is also part of the PRCM clock tree. This clock includes a pre-
divider on one of its inputs. For now we are using a custom clock
driver for it. In the future we may want to develop a generalized
driver for these types of clocks, which also includes the AHB clock
driver on sun[5678]i.

Hi Maxime,

I'll do the factors clock refactoring mentioned during the discussion
around v2 later on.
I have no idea what you are talking about :)

Same thing here, if it's only used in the A80, just compile it when
ARCH_SUN9I is compiled.
