Bluetooth: btmrvl: use native helpers for debugfs
Clean up the code by using native debugfs helpers, instead of implementing them ourselves: debugfs_create_u8() debugfs_create_x16() debugfs_create_file() debugfs_remove_recursive() Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
