ASoC: Intel: avs: Add support for FCL platform

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

The patchset is fairly straightforward - add support for Automotive
platforms based on new DSP architecture, Frisco Lake (FCL), a
PantherLake (PTL)-based platform is an example of.  The cAVS
architecture which all Intel AudioDSP followed for years ends with
RaptorLake familty.  Like all the major updates, this one received new
name too - Audio Context Engine (ACE).

While the range of improvements and changes on the firmware/hardware
side is large, software survives this evolution without need of any
major refactoring.  Additional hardware changes brought with LunarLake
(LNL, ACE 2.0) call for update in PCM-area.  The GPDMAs previously
utilized for non-HDAudio transfer types are no longer there, everything
is running through HDAudio LINK on the Back-End side now.

In terms of code, the mtl.c file, provided with patch 05 'ASoC: Intel:
avs: PTL-based platforms support' hosts largest number of new handlers -
new IRQ and INT control and DSP-cores management.  Combined with lnl.c
and ptl.c which layer the architecture changes done over ACE
generations, provide support for PTL-based platforms e.g.: FCL.
The inheritance in summary:

	mtl.c <- lnl.c <- ptl.c

The functional update to HDAudio library is there to help avs-driver
read certain capabilities directly from the hardware.  Once the pointer
to LINK is obtained, there is no need to call AudioDSP firmware to get
the caps.
