MLK-23674-2 doc: SECO MU driver binding for cmd and rsp tags
The V2X MU requires that the the sender changes the byte indication
the type of the message in its header. The value required changes
for each MU.
This patch adds the documentation of this functionality adding
explanations for fsl,cmd_tag and fsl,rsp_tag.
