Add support for the MSM8996/APQ8096 PCIe controller. MSM8996 supports Gen
1/2, one lane, 3 PCIe root complexes with support for MSI and legacy
interrupts, and it conforms to PCI Express Base 2.1 specification.
Add a post_init callback to qcom_pcie_ops, as the PCIe pipe clocks are only
setup after the phy is powered on. It also adds an ltssm_enable callback
as it is very much different from other supported SoCs in the driver.
