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.
