Bluetooth: Add variable SSP auto-accept delay support
Some test systems require an arbitrary delay to the auto-accept test cases for Secure Simple Pairing in order for the tests to pass. Previously when this was handled in user space it was worked around by code modifications and recompilation, but now that it's on the kernel side it's more convenient if there's a debugfs interface for it.
