PCI: qcom: Make sure PCIe is reset before init for rev 2.1.0
commit d3d4d02 upstream. Qsdk U-Boot can incorrectly leave the PCIe interface in an undefined state if bootm command is used instead of bootipq. This is caused by the not deinit of PCIe when bootm is called. Reset the PCIe before init anyway to fix this U-Boot bug.
