If the gcm cipher used by rfc4543 does not complete request immediately,
the authentication tag is not copied to destination buffer. Patch adds
correct async logic for this case.

The GMAC code assumes that dst==src, which causes problems when trying to add
rfc4543(gcm(aes)) test vectors.
So fix this code to work when source and destination buffer are different.

timeriomem_rng only supports a single device instance. This patch
enables multiple timeriomem_rng devices to coexist as well as adds
some additional error checking.

Occurs when CONFIG_CRYPTO_CRC32C_INTEL=y and CONFIG_CRYPTO_CRC32C_INTEL=y.
Older versions of bintuils do not support the pclmulqdq instruction. The
PCLMULQDQ gas macro is used instead.

These modules require AVX support in assembler, so add new check to Makefile
for this.
Other option would be to use CONFIG_AS_AVX inside source files, but that would
result dummy/empty/no-fuctionality modules being created.
