PCI/doc: Update obsolete pci_set_dma_mask() references 

The function is dma_set_mask(), fix a missed instance of the old
pci_set_dma_mask() and a reference to a function that doesn't exist.

While all drivers should explicitly indicate the DMA capability

32-bit bus master capability for streaming data need the driver

Drivers for all PCI-X and PCIe compliant devices must call
