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.

Servicing IPCs on CNL platforms and onward differs from the existing
one. To make room for these, relocate SKL-based platforms specific code
into the skl.c file leaving only the genering irq_handler in the common
code.

Prefix members that are platform-specific with 'avs_' to improve code
cohesiveness and reduce the chance for naming-conflics with other
drivers.

Without debug filesystem present, this code is redundant.
Operations: log_buffer_status and log_buffer_offset are left as is as
EXCEPTION_CAUGHT and even unexpected LOG_BUFFER_STATUS notifications may
occur without user ever touching debugfs.

Define handlers specific to cAVS 1.5+ platforms, that is, APL and
similar platforms. These differ from SKL-alike ones in terms of AudioDSP
firmware generation and thus the '+' suffix. Introduciton of IMR,
removal of CLDMA, D0IX support and monolithic-ation of library/module
code are most impactful but are not the only changes brought with this
newer generation. Some generic and 1.5 operations are being re-used to
reduce code size.
