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:
(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);
