Subject: usb: host: fsl-mph-dr-of: use of_property_read_bool

Use of_property_read_bool to check for the existence of a property.

The semantic patch that makes this change is as follows:

expression e1,e2,x;

-	if (of_get_property(e1,e2,NULL))
-		x = true;
-	else
-		x = false;
+	x = of_property_read_bool(e1,e2);
