qfprom_disable_fuse_blowing() disables a bunch of resources, and then does a few register writes in the 'conf' address space. It works perhaps because the resources are needed only for the 'raw' register space writes, and that the 'conf' space allows read/writes regardless. However that makes the code look confusing, so just move the register writes before turning off the resources in the function.
