feat(ti): implement DM_MANAGED suspend

DM_MANAGED is the new mode to support a model where DM chooses the
suspend mode. Previously suspend always chose deep sleep. Now DM may
also choose other modes like IO+DDR or other modes in the future. DM has
more knowledge about constraints regarding wakeup latency or which parts
of the system need to work continuously, so it is better able to decide
what suspend mode should be used.

To support DM_MANAGED in TF-A the next system mode needs to be fetched
and passed to the enter sleep message. The new ti_sci command to fetch
the next system mode is added which is ti_sci_lpm_get_next_sys_mode().

DM_MANAGED is only enabled if the firmware capability is supported.
