[PATCH] PCI: sysfs: Update ROM to include default owner write access

[Alex Williamson <alex.williamson@redhat.com>]

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.
