hv: dm: Use new pci device passthrough management ioctls

Browse Source 
IC_ASSIGN_PCIDEV		->	ACRN_IOCTL_ASSIGN_PCIDEV
IC_DEASSIGN_PCIDEV		->	ACRN_IOCTL_DEASSIGN_PCIDEV
QUIRK_PTDEV			->	ACRN_PTDEV_QUIRK_ASSIGN
struct acrn_assign_pcidev	->	struct acrn_pcidev

Move struct acrn_pcidev into acrn_common.h because it is used by both
DM and HV.
