The first and second ones are similar to the ones on A64, but the third one adds EMCE (Embedded Crypto Engine) support which does hardware transparent crypto on the eMMC. As we still do not have support for EMCE, and the support of it is disabled by defualt, we just duplicate the A64 mmc configurations and change the compatible string.
