scsi: ufs: core: Add support for qTimestamp attribute
The new qTimestamp attribute was added to UFS 4.0 spec, in order to
synchronize timestamp between device logs and the host. The spec recommends
to send this attribute upon device power-on Reset/HW reset or when
switching to Active state (using SSU command). Due to this attribute, the
attribute's max value was extended to 8 bytes. As a result, the new
definition of struct utp_upiu_query_v4_0 was added.
