drivers: thermal: Add shared interrupt handler support to LMH DCVS 



Add support for shared interrupt handler to LMH DCVS. It helps to
notify scheduler properly for target which has common LMH hardware
and different clock domains.

Ignore thermal zone register error in case if thermal zone is not
defined for the shared LMH DCVS instance.
