m7-common: move CDMA Telephony overlays to devices

These overlay settings are applicable to m7spr and m7vzw only, and
should be applied to more spns than 310120/311480. Move them out of
common and into the correct overlay structure for each device.

m7-common: use new offmode_charging and images

HTC incorporated charger functionality into offmode_charging and added
1% increment images. This makes offmode charging look much nicer. Also,
bring back detect_key and power_test so that the power button works to
turn-on the device from offmode.

Blobs from m7wlv 5.28.605.2.
