PATCH RESEND 1/1 via82cxxx IDE: Add VT8251 ISA bridge

Some motherboards (such as the Asus P5V800-MX) ship a PCI_DEVICE_ID_VIA_82C586_1 IDE controller alongside a VT8251 southbridge.

This southbridge is currently unrecognised in the via82cxxx IDE driver, preventing those users from getting DMA access to disks.

Bart, I submitted this 2 weeks ago but sent it to your old pw.edu.pl address by accident. Sorry about that!
