The recent change (commit 08422d2c55: "ALSA: memalloc: Allow NULL
device for SNDRV_DMA_TYPE_CONTINUOUS type") made the PCM preallocation
helper accepting NULL as the device pointer for the default usage.
Drop the snd_dma_continuous_data() usage that became superfluous from
the callers.

The build of aica sound driver has been broken since the timer API
conversion and some code rewrite. This patch fixes the breakage by
using the common substream field, as well as a bit cleaning up wrt the
timer handling in the code.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This requires adding a pointer to
hold the timer's target substream, as there won't be a way to pass this in
the future.

ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

System workqueues have been able to handle high level of concurrency
for a long time now and there's no reason to use dedicated workqueues
just to gain concurrency. Since aica_queue for AICA sound
driver has workitem dreamcastcard->spu_dma_work (maps to run_spu_dma)
which is involved in aica dma transfers and is not being used on a memory
reclaim path, dedicated aica_queue has been replaced with the
use of system_wq.
Unlike a dedicated per-cpu workqueue created with create_workqueue(),
system_wq allows multiple work items to overlap executions even on
the same CPU; however, a per-cpu workqueue doesn't have any CPU
locality or global ordering guarantees unless the target CPU is
explicitly specified and thus the increase of local concurrency
shouldn't make any difference.
Since the work items could be pending, flush_work() has been used in
snd_aicapcm_pcm_close() to ensure that there is no pending task while
disconnecting the driver.
