[rv_dm] Make the RV_DM a comportable module

This makes the RV_DM a comportable IP module.
To this end, an Hjson description is created, leveraging the recently
added topgen feature that allows for multiple TL-UL interfaces per
comportable IP.

This patch also modifies some of the interface signals to be compatible
with the intersignal mechanism in topgen, and it adds the alert
integrity alerts.
