arm/dt: pm8974: Specify MPM pin connected to USB3 hs_phy_irq

hs_phy_irq is used to receive asynchronous events from USB3
hardware in LPM. Specify MPM pin to which this interrupt is
connected so that system can use this as wakeup source.
Also, correct MPM pin number for USB2 IRQ which should be
mapped to 2nd HSPHY irq instead of one coming from 1st HSPHY
as USB2 controller uses 2nd HSPHY.
