Subject: [PATCH 0/3] arm64: dts: qcom: fix USB wakeup interrupts again (pt 2)

The USB DP/DM HS PHY interrupts need to be provided by the PDC interrupt
controller in order to be able to wake the system up from low-power
states and to be able to detect disconnect events, which requires
triggering on falling edges.

A recent commit updated the trigger type but failed to change the
interrupt provider as required. This leads to the current Linux driver
failing to probe instead of printing an error during suspend and USB
wakeup not working as intended.

While at it, fix also the SS PHY interrupt so that it too can be used to
wakeup the system up.

Thanks to Konrad and Krishna for providing the sdm670 PDC interrupts
numbers. The sc8180x SS PHY vectors I inferred from sdm670/sdm845/sm8150
which appear to use the name configuration.

After this series, only sm6375 remains to be fixed and I believe Bjorn
is trying to dig out the corresponding vectors.

Also note that these patches have only been compile tested.
