Subject: [PATCH] drm: Use static attribute groups for managing connector sysfs
 entries

Instead of manual calls of device_create_file() and
device_remove_file(), assign the static attribute groups to the device
with device_create_with_groups().  The conditionally built sysfs
entries are handled via is_visible callback.

This simplifies the code and also avoids the possible races.
