board/qualcomm: introduce phone config

Browse Source 
Phones don't have keyboards! Introduce a phone-specific config fragment
and associated environment file to make U-Boot more useful on these
devices. This allows for navigating via the buttons and enabling
various USB gadget modes or displaying info about U-Boot.
