msm: thermal: Add support for CX ipeak LM monitor and mitigation

Add support for CX junction temperature monitor and thermal client
vote to CXIP LM hardware in KTM. When all pre-defined clients on
CX rail including thermal client set their vote, CXIP LM hardware
throttles pre-defined client on the same rail. During boot up,
KTM will set a pre-defined bypass clients bits of CXIP LM hardware
and monitors pre-defined tsens for preset threshold. Once it triggers,
it will vote for CXIP LM and clears vote when preset clear threshold
is reached. KTM enables this feature only if devicetree entry
'qcom,cxip-lm-enable' is configured with a non zero value.
If value is zero, then it disable this hardware feature explicitly.
