After commit 77dccad986 ("ipc: moving src/ipc/*-ipc.c files to drivers
dir") there is no need to use byt or hsw prefix because the file is
already in the platform specific directory.

On some systems the DSP has no DMA interface to the host and is
using a serial port for sending its trace. This patch adds a "-u"
argument to specify a baudrate, that should be used with the serial
interface. The implementation takes care of spurious bytes,
sometimes seen in the beginning of the trace, produced by the port
initialisation by the DSP. The format is fixed to 8N1.

1. Programs shouldn't exit with negative return values, strictly
speaking only EXIT_SUCCESS and EXIT_FAILURE should be used,
however it is also valid to return 0 for success and any number
from 1 to 125 for a failure.
2. Avoid passing complete structs as function parameters where an
additional copy of one isn't needed, use const pointers instead.
3. Remove a left-over unused argument.

memory.h for the SUE Creek platform currently contains several
definitions, copied over from other platforms, having a direct
memory-based connection between the host CPU and the DSP, that
aren't relevant for the SUE Creek. Remove those definitions.

I've moved src/ipc/*-ipc.c to src/drivers/intel directory
each for specific platform. I've merged apl-ipc.c and
cnl-ipc.c using CONFIG_* defines and placed the result
file ipc.c in src/drivers/intel/cavs.

The linker script on platforms, using the boot-loader places the .text
section at SOF_TEXT_BASE, not at SOF_TEXT_START, the same name should be
used for the start address in assembly even though so far on all
platforms both names refer to the same location.

This patch adds a volume component after SRC to be able to convert
the variable pipeline s16/s24/s32 PCM format into PCM format used
by DAI. The PCM capabilities are changed to allow all formats.

With this patch the S16_LE format becomes supported in addition
to S24_4LE and S32_LE. The generic C, HiFiEP, and HiFi3 versions
are updated. The patch changes the s24 polyphase algorithm for
s16 data and changes the s32 algorithm for both s24/s32 support
with a shift by 0 or 8 parameter.
As done for other components too the PCM format handling is moved
from params() to prepare() function since the actual pipeline
format didn't appear correctly in params().
The patch removes the own ceil_divide() function since it's
provided by math library. Also some code indents are fixed.

broadwell and haswell linker scripts are identical, by removing
broadwell-specific file for linker script we have cleaner buildsystem
where all linker scripts have names just like platform folder names

For dais, we don't support change dma channel dynamically, so only get
dma channel at first config, ignore that for latter dai_config
invokings to avoid dma channel leaking.

This patch removes from FIR and IIR EQs the check if array data pointer
is null. Since it is an array the test evaluates as true and the check is
unnecessary.

This patch prevents the host component from flooding the trace when
audio playback or capture rate is other than 48 kHz. It only means
that the host sink buffer still has samples unconsumed by the
downstream component. This is not a warning so it's better to change
it to tracev_host().
