Manivannan Sadhasivam 6c1a7c00ba PCI: qcom-ep: Disable resources unconditionally during PERST# assert
[ Upstream commit 912315715d ]

All EP specific resources are enabled during PERST# deassert. As a counter
operation, all resources should be disabled during PERST# assert. There is
no point in skipping that if the link was not enabled.

This will also result in enablement of the resources twice if PERST# got
deasserted again. So remove the check from qcom_pcie_perst_assert() and
disable all the resources unconditionally.

Fixes: f55fee56a6 ("PCI: qcom-ep: Add Qualcomm PCIe Endpoint controller driver")
