This series cleans up the filesystem core. The great goal of this series is to
allow unmounting a fileystem by just unregistering the device.
unmount already goes down to unregister a device, but unmount also cleans up
the allocated ressources. We move the filesystem drivers/devices to their own
bus which allows us to clean up the resources in the busses remove function so
that a filesystem can be unmounted *and* cleaned up by unregistering the device.
With this series (and the preceding one) it's possible to call the 'usb' command
on a panda board multiple times without crashing barebox. I tested this with
the onboard USB network adapter and a USB flash drive with a FAT mounted.
