crypto: drbg - Use Kconfig to ensure at least one RNG option is set
This patch removes the build-time test that ensures at least one RNG is set. Instead we will simply not build drbg if no options are set through Kconfig. This also fixes a typo in the name of the Kconfig option CRYTPO_DRBG (should be CRYPTO_DRBG). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
