Make it clear what is part of debug functionality and what is not by
separating debug symbols away from the common header file.

Apart from changing avs_probe_platform_register() to return -ENOTSUPP
when CONFIG_DEBUG_FS is disabled, status quo is achieved.

The snd_hdac_adsp_xxx() wrap snd_hdac_reg_xxx() helpers to simplify
register access for AudioDSP drivers e.g.: the avs-driver. Byte- and
word-variants of said helps do not expand to bare readx/writex()
operations but functions instead and, due to pointer type
incompatibility, cause compilation to fail.

As the macros are utilized by the avs-driver alone, relocate the code
introduced with commit c19bd02e9029 ("ALSA: hda: Add helper macros for
DSP capable devices") into the avs/ directory and update it to operate
on 'adev' i.e.: the avs-driver-context directly to fix the issue.

For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.

Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

Most IRQ-related code is duplicated in the driver. Switch to the new
implementation and remove unused members.

While the change is non-trivial, from functional perspective status quo
is achieved.

The existing code can be both improved and simplified. To make this
change easier to manage, first add new implementation and then remove
deadcode in a separate patch.

Simplification achieved with:
- reduce the amount of resources requested by the driver i.e.: IPC and
  CLDMA request_irq() merged into one
- reduce the number of DSP ops from 2 to 1:
  irq_handler/thread() vs dsp_interrupt()
- drop ambiguity around CLDMA interrupt, let skl.c handle that
  explicitly as it is the only user

Define handlers specific to cAVS 1.8 platforms, that is CNL, CFL, CML
and all other variants based on this very version of AudioDSP
architecture. Most operations are inherited from their predecessors.
