X1 has multiple DWC3 hosts, including one that's USB2, which naturally
means it doesn't have a SuperSpeed interrupt. Make it optional to fix
warnings such as:

usb@a2f8800: interrupt-names: ['pwr_event', 'dp_hs_phy_irq', 'dm_hs_phy_irq'] is too short

That's a good start, but what about all the other warnings for usb 
interrupts?:

     13  usb@f92f8800: 'interrupt-names' is a required property
     11  usb@76f8800: interrupt-names: ['pwr_event', 'qusb2_phy', 'hs_phy_irq'] is too short
     11  usb@6af8800: interrupts: [[0, 347, 4], [0, 243, 4]] is too short
     11  usb@6af8800: interrupt-names:1: 'qusb2_phy' was expected
     11  usb@6af8800: interrupt-names:0: 'pwr_event' was expected
     11  usb@6af8800: interrupt-names: ['hs_phy_irq', 'ss_phy_irq'] is too short
      9  usb@a2f8800: interrupt-names: ['pwr_event', 'dp_hs_phy_irq', 'dm_hs_phy_irq'] is too short
      7  usb@c2f8800: interrupt-names: ['pwr_event', 'qusb2_phy', 'hs_phy_irq'] is too short
      5  usb@8af8800: interrupts-extended: [[1, 0, 134, 4]] is too short
      5  usb@8af8800: interrupt-names: ['pwr_event'] is too short
      4  usb@8af8800: interrupts: [[0, 62, 4]] is too short
      4  usb@8af8800: interrupt-names: ['hs_phy_irq'] is too short

I'll address most of those shortly. Need to dig up a couple old devices
to make sure my findings reflect reality ;)
