ARM: dts: msm: Add BCL thermal zone mitigation for msm8909w-pm660

Add BCL mitigations for BCL events like battery voltage, current and
low SoC thresholds for msm8909w-pm660. The BCL module will mitigate
the CPU's, when battery reaches the low voltage threshold,
high current threshold or low state of Charge.

Remove old thermal/BCL framework related devicetree nodes for
msm8909w-pm660 variants.
