[PATCH 07/11 v2] phy: qcom-ufs: use of_property_read_bool

[Julia Lawall]

Use of_property_read_bool to check for the existence of a property.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e1,e2,x;
@@
-       if (of_get_property(e1,e2,NULL))
-               x = true;
-       else
-               x = false;
+       x = of_property_read_bool(e1,e2);
// </smpl>
