drm: omapdrm: Deconstruct the omap_drv.h header. The number of function declarations in the omap_drv.h degrades readability. To fix it, create new header files for each part of the driver and move the related functions.

drm/omap: Determine connector type directly in omap_connector.c Instead of determining the connector type from the type of the display's omap_dss_device and passing it to the omap_connector_init() function, move the type determination code to omap_connector.c and remove the type argument to the connector init function. This moves code to a more natural location, making the driver easier to read.

drm/omap: Merge HPD enable operation with HPD callback registration The omap_dss_device .enable_hpd() and .disable_hpd() are used to enable and disable hot-plug detection at omapdrm probe and remove time. This is required to avoid reporting hot-plug detection events before the DRM infrastructure is ready to accept them, as that could result in crashes or other malfunction. Hot-plug event reporting is conditioned by both HPD being enabled through the .enable_hpd() operation and by the HPD callback being registered though the .register_hpd_cb() operation. We thus don't need a separate enable operation if we can guarantee that callbacks won't be registered too early. HPD callbacks are registered at connector initialization time, which is too early to start reporting HPD events. There's however nothing blocking a move of callback registration to a later time when the omapdrm driver calls the HPD enable operations. Do so, and remove the HPD enable operation completely from omap_dss_device drivers.
