Subject: [PATCH 02/11] arm64: dts: qcom: sa8775p: fix USB wakeup interrupt types

The DP/DM wakeup interrupts are edge triggered and which edge to trigger
on depends on use-case and whether a Low speed or Full/High speed device
is connected.

Note that only triggering on rising edges can be used to detect resume
events but not disconnect events.
