crypto: ansi_cprng - Move FIPS functions under CONFIG_CRYPTO_FIPS
fips_cprng_get_random and fips_cprng_reset is used only by CONFIG_CRYPTO_FIPS. This also fixes compilation warnings: crypto/ansi_cprng.c:360: warning: ‘fips_cprng_get_random’ defined but not used crypto/ansi_cprng.c:393: warning: ‘fips_cprng_reset’ defined but not used Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
