BE hw_params op was recently added for SSP type DAIs.
But sending the DAI_CONFIG IPC during hw_params
is not supported with older firmware. So add an ABI check
to avoid sending the IPC if the firmware ABI is older than
3.18.

Should we warn if we were trying to configure something but weren't able
to?  Seems like something has got out of sync if we're trying to do so.

      commit: 8c08652614cb7468620a6328b37ca2965cd48283

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
