Adds a new cryptographically secure pseudo random number generator known
as Fortuna. The implementation is based on the description in [0]. This
implementation replaces the implementation in LTC which was used until
now.
Gathering of entropy has been refined with crypto_rng_add_event() to
better match how entropy is added to Fortuna. A enum crypto_rng_src
identifies the source of the event. The source also controls how the
event is added. There are two options available, queue it in a circular
buffer for later processing or adding it directly to a pool. The former
option is suitable when being called from an interrupt handler or some
other place where RPC to normal world is forbidden.
plat_prng_add_jitter_entropy_norpc() is removed and
plat_prng_add_jitter_entropy() is updated to use this new entropy source
scheme.
The configuration of LTC is simplified by this, now PRNG is always drawn
via prng_mpa_desc.
plat_rng_init() takes care of initializing the PRNG in order to allow
platforms to override or enhance the Fortuna integration.
