[PATCH v4 04/10] PCI: qcom: Remove redundancy between qcom_pcie and qcom_pcie_cfg

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

In preparation to adding more flags to configuration data, use pointer
to struct qcom_pcie_cfg directly inside struct qcom_pcie, rather than
duplicating all its fields. This would save us from the boilerplate code
that just copies flag values from one struct to another one.
