This BUG_ON() happens if a mite DMA channel is already requested when an
ansynchronous command is started for one of the counter subdevices.
The comedi core will only call the (*do_cmd) if the subdevice is not busy.
In this driver, the (*cancel) for the subdevice will always release any
requested mite DMA channel.
Remove the BUG_ON() which can never occur.

The BUG_ON() checks in the helper functions are not necessary. The mite
driver quiries the PCI chip to determine the number of DMA channels.
This is then used when a DMA channel is requested so the channel will
always be in range.
Convert the inline functions used to set the bits in the NI600X_DMA_CFG
register into macros. Also convert the associated enum dma_selection.
This clarifies the association with the register.
Rename the associated 'dma_configuration_soft_copies' member of the
private data to allow shorting some of the ugly long lines in the
driver.
This also fixes a number of checkpatch.pl issues about:
