[PATCH] ARM: omap2plus_defconfig: enable NEON based crypto

* Ard Biesheuvel [off-list ref] [170906 11:48]:

Enable kernel mode NEON and the various NEON based crypto algorithms,
which are between 1.4x (AES-XTS) and 2.4x (AES-GCM) faster than
scalar code (measured on Cortex-A8).

Note that this was tested using the updated GHASH code that is queued
for v4.14

Applying finally into omap-for-v4.15/defconfig thanks.
