aaudio: convert mono output to stereo
MMAP hardware streams are often stereo.
But apps often want to output a mono stream.
Since converting from mono to stereo is easy,
we can go ahead and open a stereo hardware stream
and then just convert the apps mono data to stereo for the HW.
Add getDeviceChannelCount().
