ASoC: SOF: add Kconfig option for strict ABI checks

Browse source 
When the kernel is more recent than firmware files, it will always
behave in backwards-compatible ways.

Add optional behavior to check if the kernel is older than the
firmware files, so that the kernel fails early instead of attempting
to use new functionality it does not support.

This option enables strict ABI checks for firmware and topology
files.
When these files are more recent than the kernel, the kernel
will handle the functionality it supports and may report errors
during topology creation or run-time usage if new functionality
is invoked.
This option will stop topology creation and firmware load upfront.
It is intended for SOF CI/releases and not for users or distros.
Say Y if you want strict ABI checks for an SOF release
If you are not involved in SOF releases and CI development
select "N".
