stm32_uart: rename exported structure and add secure flag
Rename structure console_pdata into stm32_uart_pdata as it will
be exported over the platform and should not use such a generic
naming.
This change adds a secure flag to the UART device instance for
used to get the appropriate virtual address when required.
An UART bus could be used by the secure world in secure mode or
in non-secure mode. A bus to a secure element likely mandates
secure hardening of the UART. A debug console over a non-secure
UART link may require the UART resources to be assigned to the
non-secure world.

core: add new RNG implementation
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.
