Implements random noise generation interface from Arm SMCCC TRNG
specification. Configuration switch CFG_ARM_SMCCC_TRNG must be enabled
to embed the RNG driver that use this interface.
When CFG_ARM_SMCCC_TRNG is enable and CFG_WITH_SOFTWARE_PRNG is
disable, use SMCCC TRNG driver as entropy source. When
both CFG_ARM_SMCCC_TRNG and CFG_WITH_SOFTWARE_PRNG are enable, seed
OP-TEE PRNG with 32byte of TRNG entropy.
