Also add a managed functions to get a reset_ctl_bulk (array of reset_ctl)
from the device-tree.
When the device is unbound, the reset controllers are automatically
released and the data structure is freed.

I really don't like these ERR_PTR returns. I suppose they make the
code easier to port, and we can be sure that pointers will not be in
the last 4KB of address space?
It seems rather unlikely because the returned pointer points to actual
RAM allocated from the heap. On most platforms I've worked with, the top
of the address space is not dedicated to memory. If ever the need to fix
this arises it could done by tweaking the macros to use another unused
address space.
