net: broadcom: fix a mistake about ioremap resource

Commit d7a5502b ("net: broadcom: convert to
devm_platform_ioremap_resource_byname()") will broke this driver.
idm_base and nicpm_base were optional, after this change, they are
mandatory. it will probe fails with -22 when the dtb doesn't have them
defined. so revert part of this commit and make idm_base and nicpm_base
as optional.
