clk: qcom: gcc-sc8280xp: use collapse-voting for PCIe GDSCs 



The PCIe GDSCs can be shared with other masters and should use the APCS
collapse-vote register when updating the power state.

This is specifically also needed to be able to disable power domains
that have been enabled by boot firmware using the vote register.
