msg->rx_data dst here, otherwise, copying to 0 dst will
crash the firmware here.

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.

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.
This change provides a finite impulse response (FIR)
equalizer component. The FIR equalizer can be used for any transducer or
effects equalizer needs but it is especially recommended for microphone
arrays equalization. The tool to create EQ setup blobs is included in the
rimage tools.
This change provides a tone generator component. The
purpose is to provide a high quality FW internal test signal generator for
objective audio quality measurements for component or system tests. It can
also be used as simple beep indication tones generator for users.
This change provides a sample rate converter (SRC).
The SRC is polyphase FIR type. All the conversions coefficients tables are
automatically generated by a separate Octave scripts set in the rimage
tools set. The supported in/out rates and the performance can be customized
for a different quality/resources trade-off.
Add an API to allow drivers to writeback or invalidate cache contents.
This is useful where the DSP firmware runs from cache and needs to
writeback/buffer prior to DMA or other peripheral usage.
