iio:adc:ti_am335x_adc Fix buffered mode by identifying as software buffer. ...
Whilst this part has a hardware buffer, the identifcation that IIO cares
about is the userspace facing end. It this case we push individual elements
from the hardware fifo into the software interface (specifically a kfifo)
rather than providing direct reads through to a hardware buffer
(as we still do in the sca3000 for example).
Technically the original specification as a hardware buffer could be
considered wrong, but it didn't matter until the patch listed below.
Result is that any attempt to enable the buffer will return -EINVAL
