mac80211: aes-cmac: switch to shash CMAC driver
Instead of open coding the CMAC algorithm in the mac80211 driver using byte wide xors and calls into the crypto layer for each block of data, instantiate a cmac(aes) synchronous hash and pass all the data into it directly. This does not only simplify the code, it also allows the use of more efficient and more secure implementations, especially on platforms where SIMD ciphers have a considerable setup cost.
