[HACK] Huge hack to keep the usb link on during HSIC re-enumeration

TODO:
- At least make it take the PHY number from the device tree, else
  the kernel will be specific to only 1 device.
- Find a suitable API to hook that better.
  - USB Hubs have a PORT_RESET feature.
    See toolhub_ctl.pyin the gnuk git at https://git.gniibee.org/
    for more details.
  - RFKILL would probably not be accepted upstream because it's
    only meant to cut radio emmissions (like cutting transmitting
    antenna power).

Here's the boot log:
