Log Message:
viaide(4): add UDMA support for VT8233C IDE controller.

The VT8233C is another obscure VIA southbridge and appears to be a variant of the
VT8233 rather than the VT8233A (which supports ATA133). The C variant was paired with
a 3Com network controller instead of VIA’s own NIC. Detect the ISA–PCI bridge and
enable UDMA100 capability for improved IDE performance.

Update the viaide(4) man page and refine the list of supported VIA controllers.
