Subject: Don't hard code the location of m5AlphaAccess.  Instead, move the
 code into a function that can be called by the AlphaConsole class.
 AlphaConsole will pass in its address.

arch/alpha/ev5.hh:
    Move Phys2K0Seg to ev5.hh and fixup the TSUNAMI uncacheable
    bits so that they will be converted correctly.
dev/alpha_access.h:
    Do not hard code the location of the AlphaConsole
dev/alpha_console.cc:
    fixup #includes
    tell the system where the alpha console is
sim/system.hh:
    Provide a function that will tell the system where the AlphaAccess
    structure (device) lives
