thermal/drivers/qcom/lmh: Add support for sm8150 



Add compatible to support LMh for sm8150 SoC.
sm8150 does not require explicit enabling for various LMh subsystems.
Add a variable indicating the same as match data which is set for sdm845.
Execute the piece of code enabling various LMh subsystems only if
enable algorithm match data is present.
