ARM: dts: msm: Remove TSENS QFPROM address and slope data

TSENS (Temperature sensor) driver does not need to map the
QFPROM region to obtain the gain and offset since these are
programmed in the boot initialization to the controller.
This removes the dependency for the application TSENS driver
to map the QFPROM physical region. Hence remove this property
as its optional. Also remove the default slope values that
are used in cases where the application TSENS driver uses it
for calibrationless mode.
