Some devices have a really long power-on cycle, and we fail to
successfully probe these if they're plugged in and then turned on.

There's really no down-side to bumping the number of retries and the
retry delay, and most devices will get picked up within the first couple
of retries anyway.

We dynamically create an attribute group for the key present on the
device in hand and point device->group to it.  This way the device
core adds the sysfs attributes for us as the device is added.

We export the entire config rom, so this is technically redundant,
but should make udev rules and HAL integration easier.

The device_type struct is useful for setting attributes for a device
and overriding .release and .uevent for a group of devices.  This patch
uses it this way to clean up the sysfs code a bit.

This serializes the update callback with the probe and remove callback from
the driver core and prevents remove from being called while update is
running for the same device.

Drop the event list semaphore and only use the wait queue and the list

Instances of struct file_operations and struct fw_card_driver can be
qualified as "const".  Ditto with struct fw_descriptor.data, struct
fw_device_id, and predefined instances of struct fw_address_region,
at least in the current implementation.

Data qualified as const is placed into the .rodata section which won't
be mixed with dirty data.
