Bluetooth: Convert debug files to actually use debugfs instead of sysfs
Some of the debug files ended up wrongly in sysfs, because at that point of time, debugfs didn't exist. Convert these files to use debugfs and also seq_file. This patch converts all of these files at once and then removes the exported symbol for the Bluetooth sysfs class. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
