[PATCH v7 6/7] PCI: qcom: Disable ASPM L0s and remove BDF2SID mapping config for X1E80100 SoC

From: Qiang Yu
Date: Wed Oct 16 2024 - 23:06:20 EST


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, hence don't
need config_sid() callback and hardware team has recommended to disable
L0s as it is broken in the controller. Hence reuse cfg_sc8280xp for
X1E80100.
