drm/omap: fix uninit order in pdev_remove() 

When unloading omapdrm driver, the omapdrm platform device is
uninitialized last, after the displays have been disconnected omap_crtc
callbacks have been removed. As the omapdrm pdev uninitialization needs
the features uninitialized in earlier steps, a crash is guaranteed.

This patch fixes the uninitialize order so that the omapdrm pdev is
removed first.
