ASoC: amd: acp: bounds-check SoundWire link ID in machine drivers
Add a bounds check in create_sdw_dailink() to validate that the
SoundWire link ID derived from link_mask does not exceed the maximum
supported by the platform. If the link ID is out of range or link_mask
is zero, log an error and return -EINVAL to prevent accessing invalid
CPU pin ID tables.
Applied to both acp-sdw-sof-mach.c and acp-sdw-legacy-mach.c.
