[PATCH] crypto: tegra: Add crypto config in tegra_cmac_do_final()

[Wentao Liang <vulab@iscas.ac.cn>]

The function tegra_cmac_do_final() calls the function tegra234_aes_cfg(),
but does not call tegra234_aes_crypto_cfg() to have a crypto
configuration. A proper implementation can be found in
tegra_ccm_do_ctr().

Add the tegra234_aes_crypto_cfg() for configuration.

Fixes: 0880bb3b00c8 ("crypto: tegra - Add Tegra Security Engine driver")
