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

[ 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.
