pass the location of the m5 backdoor via the m5AlphaAccess variable

Browse source 
only compile one console

console/Makefile:
    Now that the location of the m5 backdoor is passed into the
    console via the m5AlphaAccess variable, we only need to
    compile one console, and don't need to define TLASER or TSUNAMI
console/console.c:
    Don't hardcode the location of the AlphaAccess structure, but
    rely on m5 to pass in the correct value.
    Setup "volatile struct AlphaAccess *m5AlphaAccess" for use and
    get rid of the hardcoded usage.
