Johan Hovold 9e4810b4e1 PCI: qcom: Fix pipe clock imbalance
commit fdf6a2f533 upstream.

Fix a clock imbalance introduced by ed8cc3b1fc ("PCI: qcom: Add support
for SDM845 PCIe controller"), which enables the pipe clock both in init()
and in post_init() but only disables in post_deinit().

Note that the pipe clock was also never disabled in the init() error
paths and that enabling the clock before powering up the PHY looks
questionable.
