docs: staging/tee.rst: convert into definition list

Fix the following warnings:

tee.rst:65: WARNING: Unexpected indentation.

tee.rst:69: WARNING: Block quote ends without a
blank line; unexpected unindent.

By switching to the 'definition list' syntax.

 TEE bus infrastructure registers following APIs:

-   probed via corresponding probe API registered by the client driver. This

 TEE bus device enumeration is specific to underlying TEE implementation, so it
 is left open for TEE drivers to provide corresponding implementation.
