radeonfb: Use pci_dev pm_cap

Browse Source 
Use the already existing pm_cap variable in struct pci_dev for
determining the power management offset.  This saves the driver from
having to keep track of an extra variable.  Also, use the pci_power_t
value instead of always using the raw value for PCI_D2.
