The FW_CDEV_IOC_GET_INFO ioctl looks at client->device->config_rom, not
at the local node's config ROM.
We could fix the implementation or the documentation. I believe the way
how it is currently implemented is more useful than the way how it is
currently documented. In fact, libdc1394 uses the ABI already as
implemented, not as documented. Hence let's change the documentation.

This duplicates the read cycle timer feature of raw1394 (added in Linux
2.6.21) in firewire-core's userspace ABI. The argument to the ioctl is
reordered though to ensure 32/64 bit compatibility.

The isochronous packet format is still not documented, but this
is a good first step.

The struct is part of the userspace interface and can not use
bitfields. This patch replaces the bitfields with a __u32 'control'
word and provides access macros to set the bits.
