Using devm_ioremap_resource() API to simplify the code.
Signed-off-by: Firo Yang <firogm@xxxxxxxxx>

According to Julia's advices:
The patch "[PATCH v2] ARM: pxa: ssp: remove unnessary free for devm_xxx"
submited by Firo Yang should be discard. It was obsoleted by
"[PATCH] ARM: pxa: ssp: remove unnessary free for devm_xxx"
and
"[PATCH] ARM: pxa: ssp: Use devm_ioremap_resource instead of devm_ioremap"
I am not sure whether it was clear. If there is any doubt, please
email me.
