Add the initial configuration for clocks that need default parent and rate
setting. This is based on the vendor tree clock provider parents and rates
configuration except this is doing the setup in dts rather than using clock
consumer API in a clock provider driver.

Changes since v1:
- removed the PCIE, CSI and DISP clocks parent setting since
that should be done from their driver.

Thanks Abel, this helps audio. For audio clk:
