our first interrupt

cpu/exetrace.cc:
    added looking for symbols at PC+4 and PC+8 thanks to gcc skiping
    setting the gp where it can and jumping <func>+8
dev/console.cc:
    commented out weird interrupt per nate's suggestion
dev/tsunami_cchip.cc:
    moved rtc flag to correct bit
dev/tsunami_io.cc:
    time interrupt will be 1024Hz and at some point be configurable by
    linux
dev/tsunami_io.hh:
    Timer interrupt will be 1024hz for now and in the future be
    configurable by linux
