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. For devices running older kernels, this won't break any functionality because the interrupt configurations in QUSB2 PHY based SoCs is done by configuring QUSB2PHY_INTR_CTRL register in PHY address space and it was never armed properly right from the start.
