[PATCH resend] radeonfb: use PCI device id in hex for name string

[PATCH resend] radeonfb: use PCI device id in hex for name string

[Andreas Herrmann]

This patch slightly changes the debug output of radeonfb. E.g., instead of
printing

  radeonfb (0000:02:00.0): ATI Radeon [`

it will now show

  radeonfb (0000:02:00.0): ATI Radeon 5b60 "[`"

This will provide proper identification for all radeon cards and not
just for cards named like "Radeon X800PRO (R423) UI".


Regards,

Andreas

Additionally provide PCI device id in character format if possible.
(The printable characters were commonly used to identify the cards.)
