ANDROID: microdroid: Enable AES and POLYVAL acceleration

AVF encryptedstore uses dm-crypt and defaults to using the HCTR2
algorithm.  Enable acceleration for the components of this algorithm
using the AES and carryless multiplication instructions on arm64.  This
greatly improves performance, makes the code constant-time, and also
matches x86 which already had the equivalent enabled.
