Document the number of configurable temperature thresholds (for
trip-points in interrupt-driven mode).

Exynos5433 has the 8 interrupt for thermal. Looks good to me.

+The Exynos TMU supports generating interrupts when reaching given
+temperature thresholds. Number of supported thermal trip points depends
+on the SoC (only first trip points defined in DT will be configured):
+ - most of SoC: 4
+ - samsung,exynos5433-tmu: 8
+ - samsung,exynos7-tmu: 8

 Following properties are mandatory (depending on SoC):
 - samsung,tmu_gain: Gain value for internal TMU operation.
 - samsung,tmu_reference_voltage: Value of TMU IP block's reference voltage
