Add documentation for the phyBOARD-Pollux i.MX 8M Plus on OP-TEE
integration.
Also add missing '-' to TF-A build instruction while at it.
Would it make sense to move these instructions into a more general
section, so they could be reused by other imx based boards as well?
Seems you missed to update imx8mm-phygate-tauri-l.rst
