Adding Xc3sprog ported to SAKC

Browse Source 
Adding FPGA sram hdl code and user space code
Fixing some errors:
LCD's pinout connector is swapped
FPGA TDI SIGNAL must be routed to another pin (C14), right now is DQMH
Remove R11
Check JZ4725 symbol's component (PORTD is wrong)
Adding PB2 and PB3
wiring ADC's vref to external connector
Adding power LED
Adding CPU Led
