The LMh instances in the Qualcomm SC8180X platform looks to behave
similar to those in SM8150, add additional compatibles to allow
platform specific behavior to be added if needed.

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.

Driver enabling various pieces of Limits Management Hardware(LMh) for cpu
cluster0 and cpu cluster1 namely kick starting monitoring of temperature,
current, battery current violations, enabling reliability algorithm and
setting up various temperature limits.
The following has been explained in the cover letter. I am including this
here so that this remains in the commit message as well.
LMh is a hardware infrastructure on some Qualcomm SoCs that can enforce
temperature and current limits as programmed by software for certain IPs
like CPU. On many newer LMh is configured by firmware/TZ and no programming
is needed from the kernel side. But on certain SoCs like sdm845 the
firmware does not do a complete programming of the h/w. On such soc's
kernel software has to explicitly set up the temperature limits and turn on
various monitoring and enforcing algorithms on the hardware.
