Add the driver for SPAcc(Security Protocol Accelerator), which is a
crypto acceleration IP from Synopsys. The SPAcc supports multiple ciphers,
hashes and AEAD algorithms with various modes. The driver currently supports
below
AEAD:
- ccm(sm4)
- ccm(aes)
- gcm(sm4)
- gcm(aes)
- rfc7539(chacha20,poly1305)
cipher:
- cbc(sm4)
- ecb(sm4)
- ctr(sm4)
- xts(sm4)
- cts(cbc(sm4))
- cbc(aes)
- ecb(aes)
- xts(aes)
- cts(cbc(aes))
- ctr(aes)
- chacha20
- ecb(des)
- cbc(des)
- ecb(des3_ede)
- cbc(des3_ede)
hash:
- cmac(aes)
- xcbc(aes)
- cmac(sm4)
- xcbc(sm4)
- hmac(md5)
- md5
- hmac(sha1)
- sha1
- sha224
- sha256
- sha384
- sha512
- hmac(sha224)
- hmac(sha256)
- hmac(sha384)
- hmac(sha512)
- sha3-224
- sha3-256
- sha3-384
- sha3-512
- hmac(sm3)
- sm3

b. for aead aead_request_complete()
c. for hash ahash_request_complete()
- dt-bindings updates
a. removed snps,vspacc-priority and made it into config option
b. renamed snps,spacc-wdtimer to snps,spacc-internal-counter
c. Added description to all properties
- Updated corresponding dt-binding changes to code
v2->v3 changes:
- cra_init and cra_exit replaced with init_tfm and exit_tfm for hashes.
- removed mutex_lock/unlock for spacc_skcipher_fallback call
