[PATCH 1/2] clk: sunxi-ng: mp: provide wrapper for setting feature flags

[Andre Przywara]

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

Add a new wrapper macro that allows to specify a "features" field, to
allow marking those dual-divider clocks accordingly.
Since the MMC clocks will be a prominent user, combine this with the
postdiv field required there. Users who just want the feature, can
pass in a postdiv of 1, users of just the postdiv can pass in a feature
mask of 0.
