Subject: [PATCH v2 1/3] ALSA/ASoC/SoundWire: Intel: use single definition for SDW_INTEL_MAX_LINKS

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

The definitions are currently duplicated in intel-sdw-acpi.c and
sof_sdw.c.  Move the definition to the sdw_intel.h header, and change
the prefix to make it Intel-specific.

No functionality change in this patch.

Hi Mark,

This can't go via SoundWire tree due to machine driver conflict. Can we
go via ASoC tree?
