[PATCH] alpha: common ev6/ev7 machine check handler

Here is new ev6/ev7 machine check parser, which is a part of Jeff's
titan/marvel patchset.
Instead of fixing nautilus machine check handler, I've converted it
to use this new code.  Works fine.
Also, the CONFIG_VERBOSE_MCHECK is good for cia/pyxis - the detailed
error reporting is completely useless unless you have faulty CPU or RAM.
