Alexander Shishkin c8be489944 stm class: stm_heartbeat: Make nr_devs parameter read-only 
Changing nr_devs after the module has been loaded doesn't actually
change anything, so just make it read-only.

Alexander Shishkin 1192918530 stm class: Add heartbeat stm source device 
Heartbeat stm source may have multiple instances (for connecting to
different stm devices). Each instance will send a periodic test message
over its stm device when it is linked. This can be used for testing stm
class framework, stm device drivers or as a heartbeat over the stm link.
