Currently there is no feature capability support for ll_lt_sap
and host driver and user space assumes that support for ll_lt_sap
is always present which not always true.
This may result in unexpected behavior if firmware does not
support ll_lt_sap.
To address this issue, add a feature capability to indicate
to userspace if host driver and firmware supports ll_lt_sap.
