arm64: dts: qcom: qcm2290: Disable USB SS bus instances in park mode

commit 27f94b71532203b079537180924023a5f636fca1 upstream.

2290 was found in the field to also require this quirk, as long &
high-bandwidth workloads (e.g. USB ethernet) are consistently able to
crash the controller otherwise.

The same change has been made for a number of SoCs in [1], but QCM2290
somehow escaped the list (even though the very closely related SM6115
was there).

Upon a controller crash, the log would read:

xhci-hcd.12.auto: xHCI host not responding to stop endpoint command
xhci-hcd.12.auto: xHCI host controller not responding, assume dead
xhci-hcd.12.auto: HC died; cleaning up

Add snps,parkmode-disable-ss-quirk to the DWC3 instance in order to
prevent the aforementioned breakage.
