firmware: ti_sci: Set IO Isolation only if the firmware is capable
Prevent calling ti_sci_cmd_set_io_isolation() on firmware
that does not support the IO_ISOLATION capability. Add the
MSG_FLAG_CAPS_IO_ISOLATION capability flag and check it before
attempting to set IO isolation during suspend/resume operations.
Without this check, systems with older firmware may experience
undefined behavior or errors when entering/exiting suspend states.
Fixes: ec24643bdd62 ("firmware: ti_sci: Add system suspend and resume call")
