board: dragonboard410c: import board code from mach-snapdragon

Browse Source 
Some of the db410c board support code was written to be generic and
placed in mach-snapdragon. However, as the db410c is the only board
using this, move the code out of mach-snapdragon. This makes is more
obvious what code is relevant for which targets and helps tidy things up
a little more.
