VIDEO: cyberpro: update handling of device structures

Provide the framebuffer device with its correct parent (the PCI
device for PCI connected cards.)  Also, use this struct device to
pass to sub-drivers rather than the pci_dev structure, which is
really what they want.  Also propagate the assigned IRQ, which
they were getting direct from the PCI device structure.
