1. Add processing case branch of SOF_IPC_GLB_TRACE_MSG.
2. Add processing functions for SOF_IPC_TRACE_DMA_INIT and
SOF_IPC_TRACE_DMA_PARAMS for initlizing DMA for Trace and reply host.
3. Modify page table parsing fucntion for using in both PCM streaming and
DMA tracing case.

1. Initialize the data structure.
a) Create local DMA buffer for saving trace data.
b) Initialize the tracing work handler for syatem work queue.
2. Implement local circle buffer.
a) When the local buffer is full, empty it and reset reading/writing pointer.
3. Save the host buffer PHY addr which is parsed from IPC message. After this
config, start trace work in work queue.
4. Provide dtrace_event() for recroding trace string into local buffer.
5. Add rstrlen() utility function for getting the trace string length because
DSP side hasn't strlen().
6. Enbale trace DMA copying once every 500ms or some special cases.
a) Schedule the tracing sending work once every 500ms.
b) If the local buffer is half full, call trace sending immediately.
c) When the wrting pointer will arrive iat the end of local buffer, call
trace sending immediately.
7. Use dma_copy_to_host() function to do trace sending.

1. Add SOF_IPC_GLB_TRACE_MSG class of IPC communication.
2. Add two IPC commands for DMA tracing.
a) SOF_IPC_TRACE_DMA_INIT is used to initilize local buffer on DSP side.
b) SOF_IPC_TRACE_DMA_PARAMS is used to receive host DMA buffer PHY.
3. Define DMA for Trace params IPC info structure.

It is necessary to add dma callback to set completion_t variable to notify
DMA copying is finished. Otherwise it will always enter into error handler.

This patch adds missing S24_4LE format. Input and output format need to
be still the same. The filter coefficient set is configured in
src_config.h per platform. BYT uses a small int24 set, other use
standard int24 set. SRC wasnot unmuted by pipeline so in this version
SRC initialized to unmuted state.

This coefficient is suitable for BYT platform RAM. It provides conversions

This set prevented passtrough conversions to work, e.g. 48 kHz to 48 kHz
due to a bug in table. This set is replaced with coefficients with a
profile keyword to help selecting suitable set for a platform.

Align all components, DAIs and DMACs to use the same state levels and

This patch changes the time and timeouts used by timers from a uint32_t to a
uint64_t. This means clocks can run for years before overflow.
This patch also provides a virtual high 32 bits for HW that only has
32bit timer support. i.e. the high 32 is incremented at every HW timer
overflow.
Finally the patch updates all timer users to use uint64_t timeouts.

This patch improves robustness to various buffering settings by adding
more check for sufficient buffers sizes vs. internal block processing
length of SRC. The resize of sink buffer is changed to allow at least
internal output block length plus one period to the buffer. The bug in
rejecting disabled SRC modes is fixed in SRC core module.
