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.

- PF_0 to PF_11
Pin configuration registers for High-Drive pins.
The pin configuration registers for high-drive pins control the following pins:
• P1_17
• P2_3 to P2_5
• P8_0 to P8_2
• PA_1 to PA_3
Pin configuration registers for High-Speed pins.
This register controls the following pins:
P3_3 and pins CLK0 to CLK3.
