[PATCH] clk: qcom: gcc-glymur: use collapse-voting for PCIe GDSCs

[Taniya Das]

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

This is also needed to disable power domains that boot firmware enabled
through the vote register.

Describe the collapse-vote register and mask for every PCIe and PCIe PHY
GDSC.
