Robert Marko 55e5487ae2 PCI: qcom: Power on PHY before IPQ8074 DBI register accesses ...

[ Upstream commit a0e43bb997 ]

Currently the Gen2 port in IPQ8074 will cause the system to hang as it
accesses DBI registers in qcom_pcie_init_2_3_3(), and those are only
accesible after phy_power_on().

Move the DBI read/writes to a new qcom_pcie_post_init_2_3_3(), which is
executed after phy_power_on().
