pcnet32: use pci_set_dma_mask insted of pci_dma_supported

All drivers should be using dma_set_mask / pci_set_dma_mask to try
to set the dma mask instead of just querying it.  Without that some
iommu implementations may not work.

pci_dma_supported is removed entirely, but dma_supported stays for
dma_ops implementations for now.

This patch (of 15):

This ensures the dma mask that is supported by the driver is recorded
in the device structure.
