usb: disable tps6598x interrupts
...
Restore the interrupt masks on chainload or HV guest start. The
interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
line.
