Refactor /run/system.json for USB

[mattiaswal]

"usb-ports": [
  {
    "name": "USB",
    "path": "/sys/bus/usb/devices/usb1/authorized"
  },
  {
    "name": "USB",
    "path": "/sys/bus/usb/devices/usb1/authorized_default"
  },
  {
    "name": "USB2",
    "path": "/sys/bus/usb/devices/usb2/authorized"
  },
  {
    "name": "USB2",
    "path": "/sys/bus/usb/devices/usb2/authorized_default"
  }
]

Should be:

"usb-ports": [
  {
    "name": "USB",
    "path": "/sys/bus/usb/devices/usb1"
  },
  {
    "name": "USB2",
    "path": "/sys/bus/usb/devices/usb2"
  }
]

Pass criteria: the usb-test passes. Remember to change alder.dtsi also.

Cleaned up on my upcoming cm4 branch. No changes to alder.dtsi needed, the naming remains the same: if there's only one USB port the name is USB (from device tree) even though /sys/bus/usb/devices/usb1 is used. changes made entirely to make 00-probe work better on non-dt boards.
