spit GIC and Dispatcher Configs. Dispatcher handles only 10 service routines, now. Dispatcher can handle more than 1 service routine on a single SPI (interrupt id). Update in structure image.

small trick to add more than a single service routine to the same gpio spi 145 interrupt... in the future

initial shell beep. some assembler code to set SCTRL_EL1 is removed (it was just a comment). Try to make audio output more flexible, but dma0 audio transfer to GPIO 12/13 makes krrrrrzzt.
