clk: qcom: smd-rpm: Add a way to define bus clocks with rate and flags 



Some clocks, at least PCNoC (a.k.a CNoC_PERIPH) need to be always on,
at least on the ACTIVE side, regardless of whether they're used for bus
scaling or not.

Introduce a new macro to preset non-INT_MAX rates and clk flags to make
it easy and work implicitly through the CCF.
