The driver fetches a thermal zone using the string "cpu_thermal" for
tuning operation. Add a note for the same.

 Refer to mmc.txt for standard MMC bindings.
 
+For UHS devices which require tuning, the device tree should have a "cpu_thermal" node which maps to the appropriate thermal zone. This is used to get the temperature of the zone during tuning.
+
 Required properties:
 - compatible: Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers
 	      Should be "ti,k2g-sdhci" for K2G
