drm/tegra: remove checks for debugfs functions return value
Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail) there is no need to check the
return value of drm_debugfs_create_files(). Therefore, remove the
return checks and error handling of the drm_debugfs_create_files()
function from various debugfs init functions in drm/tegra and have
them return 0 directly.
v2: remove conversion of tegra_debugfs_init() to void to avoid build
breakage.
