The inline helper ni_stc_dma_channel_select_bitfield() returns the bits needed to select a MITE channel to use for DMA. The MITE code is setup to handle up to 8 channels but in reality only channels 0 to 3 are used by most of the drivers. The PCI-6032E and PCI-6033E boards can also use channels 4 and 5. For aesthetics, convert this inline function into a macro and remove the BUG() which will never occur.

This file is is bit of a mess. It's included by the ni_atmio, ni_mio_cs, and ni_pcimio drivers. The ni_pcimio driver is the only one that uses DMA. It defines PCIDMA so that the dma code is compiled it. This causes a bunch of ifdef'ery in the file. The DIO subdevice for the ni_pcidio "is_m_series" boards is quite different from the standard e-series DIO. Mainly it supports async commands that use DMA. Tidy up some of the ifdef'ery by adding ifdef to the subdevice init. Move the is_m_series check to the main interrupt handler so that the unneded handle_cdio_interrupt() can be blocked out for the ni_atmio and ni_mio_cs drivers. Consolidate the other ifdef's to block out the affected code.

The mite dma channels are only requested by a subdevice with a (*do_cmd) and they are released by a (*cancel).

This step of the (*do_cmdtest) fixes the timing arguments when the cmd->convert_src is TRIG_TIMER. The code is compact but it's a bit hard to understand the "burst mode" vs. "non burst mode" (i.e. paced) timing. Clarify the fixup by splitting it into separate functions to check the arguments based on if the command is doing 'paced' or 'burst' timing. Add some comments to clarify the fixups. This also fixes a minor issue with the 'burst' timing. When the cmd->scan_begin_src is also TRIG_TIMER the pacer clock is used to start each scan. The cmd->scan_begin_arg specifies the scan time. The minimum (not maximum) value for this time must be large enough for the 'burst' conversion time to sample all the channels. The current 'max' check limits the scan time to the minimum time (i.e. the max conversion speed).
