The file nx.h has function prototypes that use struct crypto_aead.
However, as crypto/aead.h is not included we don't have a definition
for it. This patch adds a forward declaration to fix this.

The Kconfig option NULL2 has been added as CRYPTO_MANAGER now
depends indirectly on NULL2. However, the Makefile was not updated
to use the new option, resulting in potential build failures when
only NULL2 is enabled.

The probe error path for this driver, for all intents and purposes,
is the talitos_remove() function due to the common "goto err_out".
Without this patch applied, talitos_remove() will panic under these
two conditions:
1. If the RNG device hasn't been registered via
talitos_register_rng() prior to entry into talitos_remove(),
then the attempt to unregister the RNG "device" will cause a panic.
2. If the priv->chan array has not been allocated prior to entry
into talitos_remove(), then the per-channel FIFO cleanup will panic
because of the dereference of that NULL "array".
Both of the above scenarios occur if talitos_probe_irq() fails.
This patch resolves issue #1 by introducing a boolean to mask the
hwrng_unregister() call in talitos_unregister_rng() if RNG device
registration was unsuccessful.
It resolves issue #2 by checking that priv->chan is not NULL in the
per-channel FIFO cleanup for loop.
