common/mlx5: update regex DevX commands

This patch modifies the SET_REGEXP_PARAMS DevX command as follows:

Remove DB setup DevX command. The command is no longer needed
in DPDK, it will always be invoked by the regex-daemon.

Add new DevX command, for programming ROF rules for a specific engine.
The command takes as an input an mkey of the ROF.
It also introduces a new field_select bit.
