clk: qcom: mmcc-msm8998: Properly consume GPLL0 inputs

Browse Source 
Up until now, the GPLL0_DIV MMSS input has been modeled as a fixed
child of MMSS_GPLL0_DIV that's always-on. Properly representing the
former in the GCC driver makes us unable to keep doing so.

Consume MSS_GPLL0_DIV through fw_name ("gpll0_div") as well as add a
fixed .name link to keep backwards compatibility.
