ASoC: rt5677: Refactor GPIO support code

After compiler complains:

sound/soc/codecs/rt5677.c:4748:30: warning: dubious: x | !y

I looked into the code and realized that we can refactor it
for better reading and fixing above issue at the same time.
Hence this change. It does not imply any functional changes.

ASoC: rt5677: Disable irq at suspend

The irq is disabled at suspend to avoid running the threaded irq
handler after the codec has been powered off. At resume, codec irq is
re-enabled and the interrupt status register is checked to see if
headphone has been pluggnd/unplugged while the device is suspended.

There is still a chance that the headphone gets enabled or disabled
after the codec is suspended. disable_irq syncs the threaded irq
handler, but soc-jack's threaded irq handler schedules a delayed
work to poll gpios (for debounce). This is still OK. The codec won't
be powered back on again because all audio paths have been suspended,
and there are no force enabled supply widgets (MICBIAS1 is disabled).
The gpio status read after codec power off could be wrong, so the
gpio values are checked again after resume.

ASoC: rt5677: Stop and restart DSP over suspend/resume

MCLK1 gets disabled at suspend and re-enabled at resume. Before
MCLK1 is re-enabled, if the DSP is already on (either the DSP was
left on during suspend, or the DSP is turned on early at resume),
i2c register read returns garbage and corrupts the regmap cache.

This patch stops the DSP before suspend and restarts it after
resume with a dalay to ensure MCLK is on while loading firmware.

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.

ASoC: rt5677: clear interrupts by polarity flip

The rt5677 jack detection function has a requirement that the polarity
of an interrupt be flipped after it fires in order to clear the
interrupt.

This patch implements an irq_chip with irq_domain directly instead of
using regmap-irq, so that interrupt source line polarities can be
flipped in the irq handler.

The reason that this patch does not add this feature within regmap-irq
is that future patches will add hotword detection support to this irq
handler. Those patches will require adding additional logic that would
not make sense to have in regmap-irq.
