We should copy from [inbox_base + offset(0 here)] src to
msg->rx_data dst here, otherwise, copying to 0 dst will
crash the firmware here.

Add support to build topology text files into binary files understood
by the drivers. This is a two stage build, the first stage is to
pre-process the files with M4 into regular alsa-conf format and the second
stage is to compile with the alsa topology compiler.

Add pipeline and token definitions to allow creation of SOF topology
files. The files define standard pipelines and tokens that can be reused
to build machine specific topology files.

SRC sets the sink and downstream pipeline PCM rate, period_count and
period_bytes in src_params() according to received out_rate via IPC.
Fail in delay lines allocation results to -ENOMEM error.
Function call comp_set_sink_params() is renamed to
comp_buffer_sink_params().
Added void to functions and corresponding headers without parameters.
Plus white space and long lines fixes for all SRC source files.

Types SOF_COMP_FILEREAD and SOF_COMP_FILEWRITE are used used in host
test bench for test vector file I/O. These components are not used in
DSP firmware.

Initialize EQ for max number of channels in configuration or switch
commands to avoid not set number of channels. A return value of -ENOMEM is
propagated in init functions and returned if allocation for memory fails.
Some trace output is added into EQ setup and some comments cleaned and
added.

A free of null pointer is fixed with this change. Also the possibility of
nondefined number of channels in EQ config or switch command is eliminated by
by initializing the FIR for max channels. An error of -ENOMEM is propagated
in functions and returned if allocation in config or switch response fails.

The default tone frequency of 997 Hz was updated to a proper Q16.16 value.
Macros for tone frequency and gain were added to tone.h and a generic
float to fractional value conversion macro to format.h. Also some common
Q1.31 decibel constants were added. Tone function pointer set was moved to
tone_new() since it is not modified later in this component.

This change provides an IIR equalizer component. The
IIR equalizer can be used for any transducer or effects equalizer needs but
it is especially recommended for speaker response equalization and other
applications without dependence to matched phase response or best possible
THD+N performance where FIR may be a better choise. IIR equalization is
capable to strong response enhancement without need for large DSP resources
consumption. The tool to create the EQ setup blobs is included in the
rimage tools.
