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.

v2->v3:
- use of_device_get_match_data to get the data from match table
rather than using of_match_device and subsequent ->data, as per
Bjorn's review comments.
- Minor fixes as per Bjorn's review comments.
v1->v2:
- Added LMH_ENABLE_ALGOS of_device_id match data to indicate
whether LMh subsytems need explicit enabling or not.
