Drivers: Intel: DMIC: Re-arrange DMIC DAI component data

This patch collects the global DMIC driver parameters into single
struct. The pointer global in every DMIC DAI instance points into
the same data. All access from functions happens via the pointer
that simplifies the next step to add NHLT binary data configuration
for the driver.

The previous dmic_prm[] is no more allocated dynamically since the
single data structure is fixed size and not large. It simplifies the
driver code that handles the multiple ownership.
