crypto: eip93 - Add Inside Secure SafeXcel EIP-93 crypto engine support

Browse Source 
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.

EIP93 have various crypto HW accelerators. Select this if
you want to use the EIP93 modules for any of the crypto algorithms.
If the IP supports it, this provide offload for AES - ECB, CBC and
CTR crypto. Also provide DES and 3DES ECB and CBC.
Also provide AEAD authenc(hmac(x), cipher(y)) for supported algo.
