Since DRBG could use SHA384/SHA512, it should select it.

if CRYPTO_DRBG_CTR is builtin and CTR is module, allocating such algo
will fail.
DRBG: could not allocate CTR cipher TFM handle: ctr(aes)
alg: drbg: Failed to reset rng
alg: drbg: Test 0 failed for drbg_pr_ctr_aes128
DRBG: could not allocate CTR cipher TFM handle: ctr(aes)
alg: drbg: Failed to reset rng
alg: drbg: Test 0 failed for drbg_nopr_ctr_aes128
DRBG: could not allocate CTR cipher TFM handle: ctr(aes)

DRBG: could not allocate CTR cipher TFM handle: ctr(aes)
alg: drbg: Failed to reset rng
ialg: drbg: Test 0 failed for drbg_nopr_ctr_aes256
Since setting DRBG_CTR=CTR lead to a recursive dependency, let's depends
on CTR=y

This should be turned into a select.

it fail also if I select it:
crypto/Kconfig:1800:error: recursive dependency detected!
crypto/Kconfig:1800: symbol CRYPTO_DRBG_MENU is selected by CRYPTO_RNG_DEFAULT
crypto/Kconfig:83: symbol CRYPTO_RNG_DEFAULT is selected by CRYPTO_SEQIV
crypto/Kconfig:330: symbol CRYPTO_SEQIV is selected by CRYPTO_CTR
crypto/Kconfig:370: symbol CRYPTO_CTR is selected by CRYPTO_DRBG_CTR
crypto/Kconfig:1822: symbol CRYPTO_DRBG_CTR depends on CRYPTO_DRBG_MENU
I forgot to say it in the commit message.
I will send a v2 with an updated commit message.
