Turn off vSafe0V interrupts. They were not being handled or cleared causing the interrupt line to be stuck low after unplugging a USB device. Also don't use read-modify-write for INT_STATUS_REG4 since this would clear the dead battery mode bit before it has been checked. BUG=b:73076662 BRANCH=none TEST=unplug USB device, see USB_C1_SWCTL_INT_ODL=1 TEST=USB2 mouse can be connected multiple times, PPC VBUS detection works, BC1.2 chip turns on and off correctly (USB_C1_BC12_VBUS_ON_L).
