staging: comedi: ni_at_a2150: introduce a2150_alloc_irq_dma()

This driver requires an IRQ and DMA in order to support async commands.

For aesthetics, introduce a helper function to request the IRQ and DMA
channels and allocate the DMA buffer. Since the async command support
is optional, make the helper function handle any request/allocation
errors and allow the driver to still attach without async command support.

staging: comedi: das1800: separate AI FIFO bounce buffer from DMA buffer

This driver can use DMA or the hardware FIFO to read analog input samples.
When DMA is enabled it's also possible for some async commands to cause
DMA to be disabled and the FIFO is used instead.

Currently the first DMA channels buffer is used for the bounce buffer
when using the FIFO. For aesthetics, add a new member to the private
