scsi: lpfc: Make FW logging dynamically configurable
Currently, the FW logging facility is a load/boot time parameter which
requires the driver to be unloaded/reloaded or the system rebooted in order
to change its configuration.
Convert the logging facility to allow dynamic enablement and configuration.
Specifically:
- Convert the feature so that it can be enabled dynamically via an
attribute. Additionally, the size of the buffer can be configured
dynamically.
- Add locks around states that now may be changing.
- Tie the feature into debugfs so that the logs can be read at any time.
