In commit 14c4e86757 ("audio: base_fw: add platform layer to IPC4
hw_config data"), the platform specific code was moved to platform
layer.
This commit implements a lighter weight abstraction for the moved
code. Instead of using the platform layer, the Intel specific vendor
code is added directly in base_fw_intel.c and guarded by a Kconfig.
All other IPC4 build targets will use an empty implementation.
This avoids the need to add a platform definition for all IPC4 targets.
The common implementation in base_fw.c is sufficient to cover all
mandatory functionality required e.g. by the upstream SOF Linux driver's
IPC4 implementation.
The interfaces are renamed to refer to "vendor" instead of "platform",
to avoid any confusion with the platform layer with the new
implementation.
