Dmitry Baryshkov 1df8231f4e thermal/drivers/qcom/lmh: Remove false lockdep backtrace 
commit f16beaaee2 upstream.

Annotate LMH IRQs with lockdep classes so that the lockdep doesn't
report possible recursive locking issue between LMH and GIC interrupts.

For the reference:

       CPU0
       ----
  lock(&irq_desc_lock_class);
  lock(&irq_desc_lock_class);

 *** DEADLOCK ***
