Log Message:
viaide(4): add IDE controller identification by the VT8237S ISA bridge.

The controller's PATA interface uses PCI ID 0x0571, which is shared among
many VIA southbridges. The ISA bridge is used to identify capabilities,
including for the VT8237S.

Unknown PATA controllers disable UDMA by default. This change ensures PATA
drives attach at full speed.

Pullups to netbsd-9 and netbsd-10 are needed.
