sunxi: add sun7i clocks and timer support. This patch adds the basic clocks and timer support for the Allwinner A20 (sun7i) processor. This code will not been compiled until the build is hooked up in a later patch. It has been split out to keep the patches manageable. Some of the code here is common to multiple sunxi subarchtectures, hence files are named sun4i which is the earliest similar variant.

sunxi: Use CONFIG_MACH_SUN?I from Kconfig instead of CONFIG_SUN?I Mostly automatic with: sed -i -e 's/CONFIG_\(SUN[45678]I\)/CONFIG_MACH_\1/g' $(git grep -l CONFIG_SUN[45678]I) followed by removing the relevant #defines from include/configs/sun?i.h by hand.
