[media] Rename media/dvb as media/pci

The remaining dvb drivers are pci, so rename them to match the
bus.

+	  Support for PCI cards based on the Bt8xx PCI bridge. Examples are
+	  the Nebula cards, the Pinnacle PCTV cards, the Twinhan DST cards,
+	  the pcHDTV HD2000 cards, the DViCO FusionHDTV Lite cards, and
+	  some AVerMedia cards.
+
+	  Since these cards have no MPEG decoder onboard, they transmit
+	  only compressed MPEG data over the PCI bus, so you need
+	  an external software decoder to watch TV on your computer.
+
+	  Say Y if you own such a device and want to use it.
