The ALC5575 integrates an audio DSP that typically loads its firmware
from an external flash via its own SPI host interface. In certain
hardware configurations, the firmware can alternatively be loaded
through the SPI client interface. The driver provides basic mute and
volume control functions. When the SPI client interface is enabled,
firmware loading is handled by the SPI driver.
