The trace level macro is not meant to be configured directly, it takes its

Added Abstract Layer for PRNG

- Extended crypto_ops with a new prng_ops which handles prng operations.
- Replace calls to get_rng_array() with crypto_ops.prng.read(), this
enforces PRNG operations go through PRNG HAL, instead of invoking
platform-dependent PRNG implementation directly.
- Create a new mpa_set_random_generator() interface for mpa user to register
a callback to generate random number, instead of expecting the user to provide
a get_rng_array(). This enables libmpa uses crypto_ops.prng.read().
- Added a new configuration CFG_WITH_PRNG_SOFTWARE to toggle SW/HW-dependent
PRNG implementation.
- The SW PRNG implementation is supplied by backed cryto library(libtomcrypt).
- Added a new SW PRNG 'Fortuna' to libtomcrypt.
- Added a new SW PRNG 'RC4' to libtomcrypt, when Fortuna is not available due
to AES and SHA256 not available, fallback to RC4.
- Get rid of bad implemented SW PRNG in plat_vexpress(rng_support.c).
- If CFG_WITH_PRNG_SOFTWARE is not enabled, the platform needs to supply
hw_get_random_byte().
