Update Google device strings, add (PTP+ADB) id
Update Google device strings, add (PTP+ADB) id

"Nexus 4/5/7/10" is a little out of date. Update to
"Nexus/Pixel" which more accurately describes the devices
under these device ids, which includes the Pixel/Pixel XL.

Also add 0x4EE6 for the device id for the above devices in
ptp and adb mode.
