Fix the resource end in amdk8/northbridge.c.
Without this bugfix, the resource for the PCI/ISA video memory at
0xa0000 - 0xbffff is too big, i.e. it goes up to 0xcffff instead of
just 0xbffff as it should.
Here's the diff from two runs of the tool from
http://www.linuxbios.org/pipermail/linuxbios/2007-June/022449.html
on the MSI MS-7260 (K9N Neo), with and without the bugfix. After applying,
the resource size is correct again.
