Add USB and DWC3 node for tertiary port of SC8280 along with multiport
IRQ's and phy's. This will be used as a base for SA8295P and SA8295-Ride
platforms.

But I suggest you just reword this along the lines of
Add USB DWC3 multiport controller.
as it's assumed that you'll describe resources like interrupts and PHYs.
Perhaps no need to mention SA8295p either as this change is needed (and
correct) also for sc8280xp proper.

These should all be IRQ_TYPE_EDGE_BOTH as DP/DM interrupts may need to
trigger also on falling edges.
