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.

	  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.
