clk: sunxi-ng: mp: provide wrappers for setting feature flags 



So far our sunxi clock instantiation macros set the required clock
features depending on the clock type, but the new "dual divider MP
clock" requires us to pass that piece of information in by the user.

Add new wrapper macros that allow to specify a "features" field, to
allow marking those dual-divider clocks accordingly. Also add two
convenience macros that deal with the most common cases.
