Subject: [PATCH 4.4 131/131] stm class: Hide STM-specific options if STM is disabled

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 4a2e2b19f96acfc037a9773c7729d133ce1e7e3b ]

If STM=n, it doesn't make sense to ask about STM_DUMMY and
STM_SOURCE_CONSOLE support, which are not even built when enabled
anyway. Hence hide these options if STM=n.
