ALPHA: misc fixes

Browse Source 
1. arch/alpha/Kconfig

   several adjustments:
      a) additions to the systems list and cleanup of same
      b) change limits of NR_CPUS and make dep. on platform

   Note that MARVEL support is limited to 32 CPUs whan using
   42-bit KSEG - one needs 48-bit KSEG to handle up to 64, and
   we've never supported 48-bit KSEG.

2. include/asm-alpha/core_wildfire.h

   fix a typo that undoubtedly prevents WILDFIRE support
   from working
