working with acpi_device_id provided by <acpi/acpi_bus.h> work with
const acpi_device_id. So mark the non-const structs as const.

This structure is only stored in the ops field of a snd_soc_dai_driver
structure. That field is declared const, so snd_soc_dai_ops structures
that have this property can be declared as const also.
Also, make rt5514_aif_dai_ops static, as it is not used outside this
module.

Move the auto disable DSP function from the widget event "DAPM Pre" to
the set_bias_level() function to avoid the unexpected behavior. While the
SPI was recording using the DAI "rt5514-dsp-cpu-dai", the event "DAPM Pre"
would be manipulated even the DAPM widgets were not connected, and it also
would power off the DSP that cause the DSP buffered data lost. So the auto
disable DSP function should move to the set_bias_level() function to make
sure that it is only manipulated by the DAPM widgets are connected.

gcc-7 warns that there is a duplicate 'const' specifier in some
variables that are declared using the SOC_ENUM_SINGLE_DECL macro:
sound/soc/codecs/rt5514.c:398:14: error: duplicate 'const' declaration specifier [-Werror=duplicate-decl-specifier]
static const SOC_ENUM_SINGLE_DECL(
sound/soc/codecs/rt5514.c:405:14: error: duplicate 'const' declaration specifier [-Werror=duplicate-decl-specifier]
static const SOC_ENUM_SINGLE_DECL(
This removes one to fix the warning.

The rt5514 can get confused and incorrectly detect a start bit if the
SCL/SDA lines happen to both go low and then high again. This
situation has been seen to happen at reboot time and is also
theoretically possible during suspend/resume if the rt5514 keeps power
but we shut down the i2c connection.
When this happens the rt5514 is confused about the state of the i2c
bus and won't recognize its own address. That will lead to the rt5514
incorrectly NAKing the first transfer.
A single i2c transfer to any address should be enough to get the
rt5514 out of this funky state.
It is currently believed that this problem should be fixed in the
rt5514 driver itself because it seems that the i2c controller in the
rt5514 is easily confused. Most i2c devices wouldn't detect a start
bit in this case.

In rt5514_i2c_probe() if the regmap_read(RT5514_VENDOR_ID2) fails then
"val" may be left as uninitialized. Current code relies on "val" not
being RT5514_DEVICE_ID, but that's potentially unsafe.
Let's check for errors from regmap_read() and also explicitly init the
value do we're not passing a possibly uninitialized int to printk.

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

The device has multiple control interfaces, I2C and SPI. The I2C interface
mainly controls the register settings of codec. The SPI interface is in
order to provide the high speed transmission of data. For example, high
bandwidth memory read/write of DSP. The patch adds the rt5514 SPI driver
for loading the firmware of DSP and retrieving the voice data from DSP
after the system is waked up by specific voice.

This is the initial codec driver for rt5514. The codec includes a low power
DSP for voice wake up. The register address is incremental by 4 in the DSP
memory map. In order to recover the codec settings in the codec mode and
manipulate the DSP mode for voice wake up, we use the multi-level register
map. One is for ALSA API in codec mode that can be recovered by cache
before recording. Another is for DSP related settings that can be accessed
with 32bit address of the DSP in the application of voice wake up.
