[PATCH v1 04/10] PCI: qcom: do not duplicate qcom_pcie_cfg fields in qcom_pcie struct

[Dmitry Baryshkov]

In preparation to adding more flags to configuration data, use 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 flags values from one sruct to another one.
