Subject: [PATCH v3] ARM: pxa: ssp: remove unnessary free for devm_xxx

A Coccinelle warning.
It's not necessary to free memory allocated with devm_xxx
and using these free functions maybe lead to a double free that
will corrupt the resource subsys. So, I just remove them.

In "[PATCH] ARM: pxa: ssp: remove unnessary free for devm_xxx", 
I forgot to remove an unused variable struct resource *res.
