[PATCH] drivers: net: ethernet: broadcom: bcm63xx: use devm_ioremap_resource()

[Laurent Navet]

Replace calls to deprecated devm_request_and_ioremap by devm_ioremap_resource.
also remove tests on 'res' since devm_ioremap_resource() checks for it
in a better form.

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