[PATCH] thermal: mmio: remove some dead code

The platform_get_resource() function doesn't return error pointers, it
returns NULL. The way this is normally done, is that we pass the NULL
resource to devm_ioremap_resource() and then check for errors from that.
See the comment in front of devm_ioremap_resource() for more details.
