For wakeup to work, driver needs to enable interrupts that depict what is
happening on th DP/DM lines. On QUSB targets, this is identified by
qusb2_phy whereas on SoCs using Femto PHY, separate {dp,dm}_hs_phy_irq's
are used instead.
The implementation incorrectly names qusb2_phy interrupts as "hs_phy_irq".
Clean this up so that driver would be using only qusb2/(dp & dm) for wakeup
purposes.
