[ARM] arch/arm/common/sa1111.c: Correct error handling code

If it is reasonable to apply PTR_ERR to the result of calling clk_get, then
that result should first be tested with IS_ERR, not with !.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression E,E1;
@@

if (
-   E == NULL
+   IS_ERR(E)
   ) { <+... when != E = E1
        PTR_ERR(E)
       ...+> }
// </smpl>
