thermal-hal: Update get temperature API support for legacy targets

Add support for get temperature API support for legcay targets
including SDM710, QCS605, SDM660, SDM630, MSM8953, SDM632, SDM439
etc. There are targets which are binary compatible, but uses
different sensor configuration. Enable soc id based platform
detection and use different sensor configuration.
