Refactors code for underrun and overrun detection. We should report
an xrun only if DMA get data size or DMA copy fails. In other case
even 0 available copy bytes doesn't mean anything, because we are always
copying as much as possible. Buffer could potentially be filled up front.

FW sends stream position message to kernel for its version before
3.11. In kernel, no_stream_position will be set to 1 for FW version
after 3.10, and host_period_bytes will be set to 0 for other versions.
So in host_update_position, the condition is always true for hd->report_pos
>= dev->params.host_period_bytes for FW version before 3.11
Now check the condition dev->params.host_period_bytes != 0 according to

Refactors agent's functionality to really verify DSP
responsiveness. Instead of updating last_idle time
on passive level before entering waiti, let's change it
to last_check and update it on actual scheduler task
execution. Task is executed above passive level, so it
should preempt every other long running processing.
Since we don't have any additional precautions to guarantee
that low latency tick will happen exactly at the scheduled time,
let's define warning and panic thresholds to control stability

Removes buffer cache operations done based on the fact,
whether buffer is used by DMA or not. From now on DMAs have

Currently DMAs are using buffers on pipelines connected to either
host or dai components. This causes many problems in firmware logic
e.g. we need to preload playback pipelines with data or we need
to manually override buffer sizes, if the buffer isn't complaint
with specific DMA requirements. Also it requires from topology
creators to know some hardware specific things on each platform
like that for timer based scheduling on cAVS platforms we need
to have 3 periods in buffers connected to dai components.
This patch allocates separate buffers for DMAs, which are made
complaint by using different DMA attributes first. We no longer
need to preload playback streams, because we can start DMA
right away and just let it transfer zeroes before any valid
data will come.

Implements copy functions from/to DMA buffer. They take care
of cache operations and also can perform custom processing
during copy. By default it will be usual buffer copy, but in the future
it can be replaced with pcm conversions, so we don't need volume

The ESAI is a hardware DAI on the i.MX platform. This commit brings the
initial support for the ESAI.
For now, the hardware FIFO watermark is hardcoded to 96 which means that
DMA transfers will be initiated when 96 of the 128 FIFO slots are empty.
IRQ handling is disabled (but possibly not needed anyway) and the clock
divider settings are hardcoded and correct for MCLK of 49152000 Hz,
48000 Hz sample rate, 2 channels, 32-bit samples (for the codec).

This improves the performance quite significantly -- pipeline_copy on
the simple ESAI pipeline (the cs42888 pipeline) took around 781us before
while with caching I got times of 15us at a minimum (a 50-fold
improvement).
Values:
-> 0x40000000-0x5FFFFFFF: 2 (bypass, contains ADMA registers)
-> 0x80000000-0x9FFFFFFF: 1 (write-through, write allocate). This
contains almost all of the code in 0x92400000-0x92BFFFFF and all the
heaps in 0x92C00000-0x933FFFFF.
-> Everything else has cache bypass (Dummy DMA needs to be able to use
host buffers from wherever)
