Subject: [PATCH v6 7/8] PCI: qcom: Fix the cfg for X1E80100 SoC

Currently, the cfg_1_9_0 which is being used for X1E80100 has config_sid
callback in its ops and doesn't disable ASPM L0s. However, as same as
SC8280X, PCIe controllers on X1E80100 are connected to SMMUv3 and it is
recommended to disable ASPM L0s. Hence reuse cfg_sc8280xp for X1E80100.

Fixes: 6d0c39324c5f ("PCI: qcom: Add X1E80100 PCIe support")
