misc/sysmobts_misc.c: Read temperature from microcontroller
Add function for requesting the temperature information to the microcontroller. I have added a function that we can extend for requesting more information but in this case we only need to know the temperature. I have added to a microcontroller temperature handling function in the manager for monitoring this information. Signed-off-by: Alvaro Neira Ayuso <anayuso@sysmocom.de>
