drm/omap: remove checks for return value of drm_debugfs functions

Browse Source 
Since 987d65d013 (drm: debugfs: make
drm_debugfs_create_files() never fail), there is no need to ever check
the return value for drm_debugfs_create_files(). Therefore remove the
checks for the return value and subsequent error handling in
omap_debugfs_init().

These changes also enables the changing of omap_debugfs_init() to return
0 directly.

v2: convert omap_debugfs_init() to return 0 instead of void to avoid
introduction of build issues and enable individual driver compilation.
