This reverts commit eb33869c72 ("ASoC: rt5514: Guard Hotword Model bytes
loading") and commit d18420b0a0 ("ASoC: rt5514: expose Hotword Model
control")
It is discouraged to use SND_SOC_BYTES_TLV to load arbitrary bytes from
userspace to driver. Removing the 'Hotword Model' control until we have
a good way to verify the content of hotword model blobs.

This change exposes mixer control 'Hotword Model' for switching
hotword model in runtime. This new function requires updated
firmware to load hotword model at address 0x4ff80000.

Due to the DMIC that needs time to initial after the MCLK is provided, the
field of delay time is implemented by the platform data.

The volume have a step of 0.375dB, but TLV uses the units 0.01dB. It should
be changed to a step of 0.75dB to match the units of TLV.

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.
