[PATCH iwl-next v2 07/15] ice: move out debugfs init from fwlog

[Michal Swiatkowski <michal.swiatkowski@linux.intel.com>]

The root debugfs directory should be available from driver side, not
from library. Move it out from fwlog code.

Make similar to __fwlog_init() __fwlog_deinit() and deinit debugfs
there. In case of ice only fwlog is using debugfs.
