drm: convert .debugfs_init() hook to return void.
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.
