This structure is used to copy information from the 'sdw_slave'
structures, it's better to create a flexible array of 'sdw_slave'
pointers and directly access the information. This will also help
access additional information stored in the 'sdw_slave' structure,
such as an SDCA context.
This patch does not add new functionality, it only modified how the
information is retrieved.

Pass ACP pci revision id as resource data and store it in amd SoundWire
manager private data structure. This field will be used to differentiate
ACP variants.

Register mask array structure is no longer needed as except interrupt
control masks, rest of the register masks are not used in code.
Use array for interrupt masks instead of structure.

Refactor amd SoundWire manager device node creation logic and implement
generic functions to have a common functionality for SoundWire manager
platform device creation, start and exit sequence for both legacy(NO DSP)
and SOF stack for AMD platforms. These functions will be invoked from
legacy and SOF stack.
