To make pushing the usb_driver (*probe) into the comedi_driver (*auto_attach)
cleaner, factor the usb buffer allocation out of the (*probe). This also
cleans up the failure paths in the (*probe).

The 'probed' flag in the private data is used by the usb_driver (*probe)
function to find a free entry in the static usbduxsub array to use for
the comedi_device private data. The (*probe) sets this flag before it
hands off the probe to the comedi_driver (*auto_attach). The 'probed'
flag is cleared in tidy_up() are part of the usb_driver (*disconnect),
which calls the comedi_driver (*detach).
The 'probed' flag will always be set if the comedi_driver (*auto_attach)
completes successfully. The extra sanity checks in the comedi functions
are not needed. Remove them.

The bf5xx-i2s{,-pcm} and bf5xx-tdm{-pcm} drivers are nearly identical. Both are
for the same hardware each supporting a slight different subset of the hardware.
The bf5xx-i2s driver supports 2 channel I2S mode while the bf5xx-tdm driver
supports TDM mode and channel remapping. This patch adds support for TDM mode
and channel remapping to the bf5xx-i2s driver so that we'll eventually be able
to retire the bf5xx-tdm driver. Unfortunately the hardware is fixed to using 8
channels in TDM mode. The bf5xx-tdm driver jumps through a few hoops to make it
work well with other channel counts as well:
* Don't support mmap
* Translate between internal frame size (which is always 8 * sample_size)
and ALSA frame size (which depends on the channel count)
* Have special copy and silence callbacks which are aware of the mismatch
between internal and ALSA frame size
* Reduce the maximum buffer size to ensure that there is enough headroom for
dummy data.
The bf5xx-i2s driver is going to use the same mechanisms when being used int
TDM mode.
