Subject: [PATCH] TT#108000 Implement getPref function in DeviceConfig

	  * getPref will help retrieve exactly the preference
	    by name, or return a default value if preference
	    is not found; it should simplify device configs
	    a lot

Change-Id: I8e730b2f51a7819a39956879bff6cf771fb6132b
(cherry picked from commit a61d4db5b6327c763cb4ff4ec17c09f824ab663c)
