83366bcc7c crypto: eip93 - Make read-only arrays static const
Don't populate the read-only arrays sha256_init, sha224_init, sha1_init
and md5_init on the stack at run time, instead make them static.

12e0b15b19 crypto: inside-secure/eip93 - acquire lock on eip93_put_descriptor hash
In the EIP93 HASH functions, the eip93_put_descriptor is called without
acquiring lock. This is problematic when multiple thread execute hash
operations.

Correctly acquire ring write lock on calling eip93_put_descriptor to
prevent concurrent access and mess with the ring pointers.

9739f5f93b crypto: eip93 - Add Inside Secure SafeXcel EIP-93 crypto engine support
Add support for the Inside Secure SafeXcel EIP-93 Crypto Engine used on
Mediatek MT7621 SoC and new Airoha SoC.

EIP-93 IP supports AES/DES/3DES ciphers in ECB/CBC and CTR modes as well as
authenc(HMAC(x), cipher(y)) using HMAC MD5, SHA1, SHA224 and SHA256.

EIP-93 provide regs to signal support for specific chipers and the
driver dynamically register only the supported one by the chip.
