sunxi: add clock driver (UCLASS_CLK) support for sunxi
When CONFIG_CLK is defined, we now provide support for the basic clock configuration of peripherals on sunxi: * clk-sunxi-ccu.c implements the CCU based (new-style) binding based on the Linux implementation. And for handling the binding of the always-on (R_*) subsystems: * clk-sunxi-mod.c implements support for module clocks, which performs parent selection (determined via the device-tree) and determines/configures a pre-divider and divider when setting a clock-rate * clk-sunxi-gate.c: implements an clk-gate to gate individual modules (i.e. 'allwinner,sunxi-multi-bus-gates-clk') Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>

+ * CLK_DIVIDER_READ_ONLY - The divider settings are preconfigured and should
+ * not be changed by the clock framework.
