thermal: tsens8960: Add platform detection

TSENS is not supported on the MSM8960 1.0 because of a
HW bug. The driver used a platform detection mechanism
through a flag. With the 8960PRO the CPU MAJOR
version resets back to major version 1. The driver
does not distinguish the PRO parts differently and
disables the driver. Change the method to detect
the CPU using the platform detection api instead
of relying on the platform data.
