staging: comedi: addi_apci_3120: use dma_alloc_coherent()
Use `dma_alloc_coherent()` to allocate the DMA buffers instead of
using `__get_free_pages()` to allocate and `virt_to_bus()` to get the
hardware address. The coherent buffers are fairly small - at most 4
pages (although there are two of them). Use of `virt_to_bus()` is
discouraged.
Note: `struct addi_private` is used by some other ADDI-DATA drivers as
well, but this is the only one using the affected members.

staging: comedi: addi_apci_3120: don't overallocate DMA buffer
The last parameter of `__get_free_pages()` is log2 (the 'order') of the
number of pages to be allocated. This driver seems to think it is the
linear number of pages, so `apci3120_auto_attach()` first tries to allocate
16 pages, but only uses 4 of them, setting the buffer size to PAGE_SIZE
multiplied by the 'order'. If the allocation fails, it tries
progressively smaller orders, down to 0. If the allocation at order 0
succeeds, the buffer size is set to 0, which is likely to cause
problems.
Set the buffer size to `PAGE_SIZE` shifted left by the allocation order.
Since the maximum buffer size previously used was 4, start with an
allocation order of 2 instead of 4. Rename the `ui_DmaBufferPages` member of
`struct addi_private` to `ui_DmaBufferPageOrder` and rename the `pages`
local variable to `order` to make it clearer what it is.
Note: `struct addi_private` is used by some other ADDI-DATA drivers as
well, but this is the only one using the affected members.

staging: comedi: addi_apci_3120: don't allocate 2nd DMA buffer on failure
`apci3120_auto_attach()` tries to allocate two DMA buffers but may
allocate a single buffer or none at all. If it fails to allocate the
first buffer, it still tries to allocate the second buffer, even though
it won't be used. Change it to not bother trying to allocate the second
buffer if the first one fails.
