[PATCH v2 04/28] drm: omapdrm: Remove unused default display name support

[Laurent Pinchart]

The default display name is both unused and never set by platform data.
Remove default display name module parameter, platform data field and
runtime infrastructure.

Signed-off-by: Laurent Pinchart <laurent.pinchart at ideasonboard.com>

Changes since v1:

- Don't remove the platform callbacks as they're still used by the
  omapfb driver.
