scsi: ufs: core: Disable timestamp functionality if not supported 

Some Kioxia UFS 4 devices do not support the qTimestamp attribute.  Set
the UFS_DEVICE_QUIRK_NO_TIMESTAMP_SUPPORT for these devices such that no
error messages appear in the kernel log about failures to set the
qTimestamp attribute.
