scsi: ufs-qcom: enable UFSHCD_QUIRK_BROKEN_LCC
LCC (Line Control Command) are being used for communication between UFS host and UFS device. But UFS host controller on QUALCOMM Technologies have an issue with issuing the LCC commands to UFS device and hence this quirk is enabled in order to to disable LCC from the host side.
