The OTG on the Nano does not work unless the USB was started in

This series is based on patches from [1] and an additional, pending
patch [2] which removed a USB node which does not exist according to
documentation for the SoC.

The USB OTG controller cannot be used until the power-domain is enabled
unless it was started in the bootloader.
Adding the power-domain reference to the OTG node allows the OTG

Upon unbinding the device make sure we release RPi's firmware interface.

After passing the DMA buffer address through the firmware interface,
release the firmware handle, we won't need it anymore.

When unbinding the firmware device we need to make sure it has no
consumers left. Otherwise we'd leave them with a firmware handle
pointing at freed memory.
Keep a reference count of all consumers and make sure they all finished
unbinding before we do.

There's nothing special about zram and lzo. It works just fine without it, so
as long as at least one of the other supported compression algorithms is
selected.
Additionally, drop the explicit dependency from CRYPTO, as it's implied by the
selection of the algorithms themselves.
