crypto: talitos - use devm_platform_ioremap_resource()

platform_get_resource and devm_ioremap effectively open codes this.

The return type of devm_platform_ioremap_resource() is also nice as it
has multiple errors that it can return.

Because it internally calls devm_request_mem_region(), reg values and
sizes cannot overlap. This was manually verified to be the case for all
talitos users.
