the only callers of some other helpers that trigger a harmless warning

This series provides the following updtes to the Intel machine driver
Kconfig:
1. The first patch adds the explicit dependency on GPIOLIB when
SND_SOC_DMIC is selected.
2. SND_SOC_SOF_HDA_AUDIO_CODEC is required for using the legacy
HDA codec driver for HDMI support in SOF. The last 3 three patches
make the required changes to account for this.

The machine driver bdw-rt5650 (for Google buddy) supports 2 or 4-channel
recording while other two drivers support only 2-channel recording. HW
constraints are implemented to reflect the hardware limitation on BDW
platform.
Changes since v1:
- Change the patch title.
- Remove the DUAL_CHANNEL and QUAD_CHANNEL macros which are too obvious.
- Follow the naming convertion, using 'bdw_rt5650_' and 'bdw_rt5677_' to
name startup functions.
- Refine the comments in startup functions.
- Redesign the bdw_rt5650_fe_startup() function for readability.
- Add an assignment to initialize runtime->hw.channels_max variable.

Previously CLOCKING2 is set as a volatile register, but cause
issue at suspend & resume, that some bits of CLOCKING2 is not
restored at resume, for example SYSCLK_SRC bits, then the output
clock is wrong.
The volatile property is caused by CLASSD_CLK_DIV bits,
which are controlled by the chip itself. But the datasheet
claims these are read only and protected by the security key,
and they are not read by the driver at all.
So it should be safe to change CLOCKING2 to be non-volatile.

2.21.0
Hi Mark
Current snd_soc_component_driver has compr_ops,
but it is created for ALSA, not for ALSA SoC.
This means it doesn't know the callback is for which component,
thus, each callback needs to get component via lookup function.
It is not good design, and will not work in the future,
because ASoC can have multipul same name component which
current lookup function can't handle.
This v2 patch-set adds new snd_compress_ops and call
callbacks with component.
v1 is here

2.17.1
The ZL38060 is a "Connected Home Audio Processor" from Microsemi,
which consists of a Digital Signal Processor (DSP), several Digital
Audio Interfaces (DAIs), analog outputs, and a block of 14 GPIOs.
This driver supports only a tiny subset of the chip's functionality
and possible configurations:
- bypass mode (whole dsp block is bypassed)
- chip's I2S DAI routed directly to/from DACs and microphone
- chip's internal clock is driven by a 12 MHz external crystal
- chip's DAI connected to CPU is I2S, and bit + frame clock master
- chip must be strapped for "host boot": in this mode, firmware will
be provided by this driver.

Current snd_soc_component_driver has compr_ops, and each driver can
have callback via it. But, it is mainly created for ALSA, thus, it
doesn't have "component" as parameter.
Thus, each callback can't know it is called for which component.
Each callback currently is getting "component" by using
snd_soc_rtdcom_lookup() with driver name.
--- ALSA SoC ---
...
if (component->driver->compr_ops &&
component->driver->compr_ops->open)
=> return component->driver->compr_ops->open(stream);
...
--- driver ---
static int xxx_open(struct snd_compr_stream *stream)
{
struct snd_soc_pcm_runtime *rtd = stream->private_data;
=> struct snd_soc_component *component = snd_soc_rtdcom_lookup(..);
...
}
It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple same driver
name component.
To solve this issue, each callback need to be called with component.
We already have many component driver callbacks.
This patch adds new snd_compress_ops, and call it with "component".
--- ALSA SoC ---
...
if (component->driver->compress_ops->open)
=> return component->driver->compress_ops->open(
component, substream);
~~~~~~~~~
...
--- driver ---
static int xxx_open(struct snd_soc_component *component,
struct snd_compr_stream *stream)
{
=> /* it don't need to use snd_soc_rtdcom_lookup() */
...
}

EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module
found on i.MX8MN. It is different with old ASRC module.
The primary features for the EASRC are as follows:
- 4 Contexts - groups of channels with an independent time base
- Fully independent and concurrent context control
- Simultaneous processing of up to 32 audio channels
- Programmable filter charachteristics for each context
- 32, 24, 20, and 16-bit fixed point audio sample support
- 32-bit floating point audio sample support
- 8kHz to 384kHz sample rate
- 1/16 to 8x sample rate conversion ratio
