        src/sys/dev/pci: agp_intel.c agpreg.h

Log Message:
clean up the error bit clear code:
-use an aligned pci config space address as everyone else -- I'm sorry
 about that because I like gson's way a lot -- it keeps the address
 offset due to alignment visually close to the data shift --, but since
 aligned addresses are used everywhere else in definitions, this
 causes confusion
-the mask applied to the data didn't make much sense, a look at the
 FreeBSD code where this code originates from suggests that there
 was just a mistake -- one trailing zero missing --
 anyway, the datasheet tells that the error bits are all write-one-
 to-clear, so just write back the value and we are done
