The PCI sysfs ROM interface requires an enabling write to access the ROM
image, but the default file mode is 0400. The original proposed patch
adding sysfs ROM support was a true read-only interface, with the
enabling bit coming in as a feature request. I suspect it was simply an
oversight that the file mode didn't get updated to match the API.
