drivers/char/hw_random/octeon-rng.c: drop frees of devm allocated data

devm_kfree and devm_iounmap should not have to be explicitly used.

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

// <smpl>
@@
expression x,d;
@@

x = devm_kzalloc(...)
...
?-devm_kfree(d,x);
// </smpl>
