meas,* parts are in trivial-devices.yaml so move this one there
to join them.

-* TSYS01 - Measurement Specialties temperature sensor
-
-Required properties:
-
-	- compatible: should be "meas,tsys01"
-	- reg: I2C address of the sensor (changeable via CSB pin)
-
-		------------------------
-		| CSB | Device Address |
-		------------------------
-		   1         0x76
-		   0	     0x77

-Example:
-
-tsys01@76 {
-	compatible = "meas,tsys01";
-	reg = <0x76>;
-};
