AMD Elan SC520 write-protection, PCI reporting

[David Young <dyoung%pobox.com@localhost>]

I've posted at
<ftp://cuw.ojctech.com/users/netbsd-e0948978/elanopt.par.pex.patch>.
some patches that attach three new devices under the AMD Elan SC520
System Controller, elansc(4).

elanpex(4) is for PCI exception reporting.  I've found some kernel bugs
by reading the exceptions reported.  elanpar(4) protects the kernel text
from writes by the CPU and by PCI bus masters.

elanopt(4) is a work-in-progress, and it is really messy, but it activates
some optimizations.  It's based on patches sent by one Trevor Talbot to
the soekris-tech mailing list.

I've also made some miscellaneous other changes to elansc(4).
