Added JellyBean Configuration for PinMux, GPIO In/Out (work in progress).

Browse Source 
Added scu driver file scu.c.
Modified Makefile/Makefile.include to generate .map file and use -O2 as optimization.
Modified hackrf-jellybean miniblink.c to enable 1V8 and blink LED1,2&3 with configuration of PinMux and GPIO.
