Some imx system do not have IPU, so prepare the imx media drivers to support
this kind of devices. Rename the group ids to include an _IPU_ prefix, add a new
group id to support systems with only a CSI without IPU, and also
rename the create internal links to make it clear that only systems with IPU
have internal subdevices.
