shill: reload_wifi: New PCI device helper script

This script is UDEV helper function that can help restart a PCI
based wireless LAN device.  It does so by removing the PCI device
from the bus, using the EC to cycle power on the device, then
performing a bus re-enumeration of the parent bus of the device.

BUG=chrome-os-partner:25275
TEST=Manual: Force restart by modifying the driver to output an event,
and ensure the device disappears and reappears as a new phy.
