ACP6.x IP has PDM decoder block.
Create a platform device for it, so that the PDM platform driver
can be bound to this device.
Pass PCI resources like MMIO to this platform device.
Create a platform device for generic dmic codec driver.

PDM platform driver binds to the platform device created by
ACP6x PCI device. PDM driver registers ALSA DMA and CPU DAI
components with ASoC framework.

Add ACP6x irq handler for handling irq events for ACP IP.
Add pdm irq events handling.
Whenever audio data equal to the PDM watermark level are consumed,
interrupt is generated. Acknowledge the interrupt.

For the help text above here and the one below:
a. End the sentence with a period ('.').
b. Pay attention to the documented/accepted kernel style:
(from Documentation/process/coding-style.rst, section 10):
For all of the Kconfig* configuration files throughout the source tree,
the indentation is somewhat different. Lines under a ``config`` definition
are indented with one tab, while help text is indented an additional two
spaces.
