[PATCH] [POWERPC] pasemi: Broaden specific references to 1682M

[POWERPC] pasemi: Broaden specific references to 1682M
    
There will be more product numbers in the future than just PA6T-1682M,
but they will share much of the features. Remove some of the explicit
references and compatibility checks with 1682M, and replace most of them
with the more generic term "PWRficient".

This one touches drivers/char/hw_random and drivers/edac, but I'd prefer
to just merge it up through the powerpc merge path since the changes
are trivial.

(Michael, Doug, if you disagree let me know and I can submit separate
patches. This is 2.6.25 material anyway).
