firmware: ti_sci: rm: Add new ops for ring configuration
The sysfw ring configuration message has been extended to include virtid
and asel value for the ring.
Add the ASEL_VALID to TI_SCI_MSG_VALUE_RM_ALL_NO_ORDER as it is required
for DMA rings.
Instead of extending the current .config() ops - which would need same
patch change in the ringacc driver - add ti_sci_msg_rm_ring_cfg struct and
a new ops using it to configure the ring.
This will allow easy update path in case new members are added for the ring
configuration.
