mtd: rawnand: fsl_upm: Use platform_get_resource() + devm_ioremap_resource()
Replace the of_address_to_resource() + devm_ioremap() calls by
platform_get_resource() + devm_ioremap_resource() ones which allows us
to get rid of one error message since devm_ioremap_resource() already
takes care of that.
