usb: musb: dsps: fix devm_ioremap_resource error detection code
devm_ioremap_resource returns an ERR_PTR value, not NULL, on failure.
Furthermore, the value returned by devm_ioremap_resource should be tested.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e,e1;
statement S;
@@
*e = devm_ioremap_resource(...);
if (!e1) S
// </smpl>
