[PATCH v2 2/2] clk: qcom: kpss-xcc: convert to parent data API

Convert the driver to parent data API. From the Documentation pll8_vote
and pxo should be declared in the DTS so fw_name can be used instead of
parent_names. .name is changed to the legacy pxo_board following how
it's declared in other drivers.

v2:
- Change .name from pxo to pxo_board following other driver
