ASoC: rt5677: Load firmware via SPI using delayed work

The firmware rt5677_elf_vad is an ELF binary obtained from
request_firmware(). Sections of the ELF are loaded to
the DSP via SPI. A model (e.g. en_us.mmap) can optionally be
loaded to the DSP at RT5677_MODEL_ADDR to overwrite the
baked-in model in rt5677_elf_vad.

Then we switch to DSP mode, load firmware, and let DSP run.
When a hotword is detected, an interrupt is fired and
rt5677_irq() is called. When 'DSP VAD Switch' is turned off,
the codec is set back to normal mode.

The kcontrol 'DSP VAD Switch' is automatically enabled/disabled
when the hotwording PCM stream is opened/closed.

Merge tag 'asoc-v5.5' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

ASoC: Updates for v5.5

Some big changes in the core but more about cleanps and refactorings
than new features, plus a collection of new drivers and lots of small
fixes and improvements to existing ones.

- Lots more cleanups from Morimoto-san. Now that everything is a
component this is mostly about refactorings to clarify and simplify
the core, a combination of things that are no longer required due to
refactorings and spotting similarities.
- Many fixes to the Sound Open Firmware code.
- Wake on voice support for Chromebooks.
- SPI support for RT5677.
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770.

ASoC: rt5677: Add a PCM device for streaming hotword via SPI

This patch implements a PCM interface for streaming hotword
phrases over SPI. Userspace can open the PCM device at anytime.
The stream is blocked when no hotword is detected. The mic
audio buffer on the DSP is a ~128KByte ring buffer that holds
~4sec of audio samples recorded from the DMIC (S16_LE, mono,
16KHz). After a hotword is detected, previous 2 seconds of audio
(containing the detected hotword) is streamed first, then live
capture continues until userspace closes the PCM stream.

When transferring, copy one period at a time then call
snd_pcm_period_elapsed(). This reduces the latency of transferring
the initial ~2sec of audio after hotword detect since audio samples
are available for userspace earlier.
