clk: mediatek: provide common clk init function for infrasys

Browse Source 
Provide common clk init function for infrasys that defaults to topckgen
driver if clock-parent is not defined. This is the case for upstream
DTSI that doesn't provide this entry.

This is needed for infracfg driver that will make use of the unified
gates + muxes implementation.
