[SCSI] qla2xxx: Add full firmware(-request) hotplug support for all ISPs.
Transition driver to exclusively use the request_firmware() interfaces to retrieve firmware-blobs from user-space. This will be the default behaviour going forward until the embedded firmware-binary images are removed from the upstream kernel. Upon request, the driver caches the firmware image until the driver is unloaded. NOTE: The option is present to allow the user to continue to use the firmware-loader modules, but, should be considered deprecated.
