Document the bindings and update the driver to support
the PCIe phy present in Qualcomm ipq5210 SoC.

v2: Had incorrectly made both the phys as fallback. The single
    lane phy is standalone and double lane uses ipq9574 as
    fallback.

Document the PCIe phys on the ipq5210 platform. The 2 lane phy uses the
ipq9574 as fallback. The single lane phy is documented separately.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] The newly defined PHY initialization tables `ipq5210_gen3x1_pcie_ep_tx_tbl` and `ipq5210_gen3x1_pcie_ep_pcs_tbl` are never used, as the endpoint configuration mistakenly references tables from the ipq6018 SoC.

phy: qcom-qmp-pcie: Add support for ipq5210 PCIe phys

This patch adds support for a PCIe phys found on the Qualcomm ipq5210
platform.

[Severity: High]
Are the newly added ipq5210_gen3x1_pcie_ep_tx_tbl and 
ipq5210_gen3x1_pcie_ep_pcs_tbl arrays intended to be used here?

This configuration assigns the tx and pcs fields to the ipq6018 arrays, which
appears to leave the new ipq5210 tx and pcs tables entirely unused. Could this
result in incorrect PHY hardware programming for the endpoint?
