sound/soc/codecs/rt5677-spi.c does not use any miscdevice so this patch
remove this unnecessary inclusion.

An spi_driver does not need to set an owner, it will be populated by the
driver core.

Added rt5677_spi_read() and refactored rt5677_spi_write() so that
an arbitrary block in the DSP address space can be read/written
via SPI. For example, this allows us to load an ELF DSP firmware
with sparse sections, and stream audio samples from DSP ring buffer.

Create a separate module for rt5677 spi driver. Without
this patch, the build fails due to multiple defs of
'init_module' and 'cleanup_module'. module_spi_driver()
defines its own module, so it can't be part of the rt5677
module.

The ALC5677 has a programmable DSP, and there is a SPI that is dadicated for DSP
firmware loading. Therefore, the patch includes a SPI driver for writing the DSP
firmware. The VAD(Voice Activaty Detection) has be implemented and use the DSP to
recognize the key phase.
