> Enable L1SS for the i.MX6 PCIe controller when the `supports_clkreq` flag
> is set. This ensures that the PCIe endpoint can enter low-power states
> efficiently when the link is not in use.
>
> The commit a00bba406b5a ("PCI: dwc: Advertise L1 PM Substates only if
> driver requests it") clears L1SS capabilities by default. However, the
> i.MX PCIe controller supports L1SS as indicated by the settings in the L1SS
> capabilities register. By setting `dw_pcie.l1ss_support` to true when
> `supports_clkreq` is true, enable proper utilization of L1SS for i.MX6 PCIe
> configurations.
