scsi: ufs: provide a quirk to disable the LCC
LCC (Line Control Command) are being used for communication between UFS host and UFS device. New commercial UFS devices don't have the issues with LCC processing but UFS host controller might still have the issue with LCC processing, hence, added a routine to disable TX LCC on the device.
