crypto: aesni-intel - Merge with fpu.ko

Loading fpu without aesni-intel does nothing.  Loading aesni-intel
without fpu causes modes like xts to fail.  (Unloading
aesni-intel will restore those modes.)

One solution would be to make aesni-intel depend on fpu, but it
seems cleaner to just combine the modules.

This is probably responsible for bugs like:
