[PATCH 04/12] hw_random: add struct hwrng::priv member

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

A number of Linux hw_random drivers use container_of to arrive at the
driver private data, but some others use the priv member of struct
hwrng. A unsigned long worth of extra malloc space doesn't hurt, so add
the same member to barebox too.
