[PATCH] net: ethernet: freescale: use devm_ioremap_resource()

[Laurent Navet]

Replace a call to deprecated devm_request_and_ioremap by devm_ioremap_resource.
also remove tests on 'r' since devm_ioremap_resource() checks for it
in a better way.

Found with coccicheck and this semantic patch:
 scripts/coccinelle/api/devm_ioremap_resource.cocci
