This patch adds a define of 32 bit integer that equals to ASCII
string "SOF\0" to be used in checking for correct magic number in
binary data. The char type for the magic is changed to uint32_t for
simpler comparison.

This patch adds a very small size and fast to compute SRC coefficients set
for converting between 8/16/24/32/44.1/48 kHz and 48 kHz. It is
set as default for BYT platform until a more optimized SRC core is
available. The quality of this set has been reduced to achieve the faster
computation.

Currently the scheduler will schedule task based on DAI DMA interrupts.
This patch also adds the option to also schedule based on a 64 bit timer.
The scheduler will now check the tasks in the queue and it will only
run the tasks in the current window otherwise it will set a timer to
call schedule() on the next task start time (in another window).

Make sure each component checks the state transition prior to performing
any action for the new state. This ensure that only supported transitions
are used and any non supported transition is flagged as an error.
This also removes DRAIN state and performs some cleanup on mixer state
handling.

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

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 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.
