The split between the omapdss and omapdrm driver is historic and was due
to other userspace APIs (FBDEV and V4L2) being supported in addition to
DRM/KMS. Now that the drivers only supports the DRM/KMS API, there is no
need to keep them separate anymore.
Merge the two drivers and remove the now unneeded omapdrm virtual
platform device.
