Given the tests that had to be disabled for NE10, I suspect we will not
really be able to use it for CUSTOM_MODES, which should be the only time
nfft is a power of 2. So I'd suggest just disabling the support when
CUSTOM_MODES is enabled and putting in an assert.

I made this comment mostly for educational purposes. If it's too late
for NE10 to make these kind of sweeping changes to its API, I'd just not
worry about it in libopus.
