taoshan: initial import and rebase of device tree

(one more rebase coming over the next day or two)

clean up huashan old files
Remove init.device.rc

Bye-bye Init.device.rc (nice using using from huashan but you have to go now)
taoshan: overlay: change camera package name

Camera functionality was moved out of Gallery2 in 4.4(kitkat).
New package name is Camera2.
