ASoC: amd: acp: fix ffs() operator precedence for SoundWire link ID
ffs(link_mask - 1) computes ffs on (link_mask - 1) instead of
subtracting 1 from the result of ffs(link_mask). For a typical
power-of-2 link_mask this returns the wrong link ID, causing cpu_pin_id
lookup to select the incorrect SoundWire manager.
Fix the operator precedence to ffs(link_mask) - 1 in both
acp-sdw-sof-mach.c and acp-sdw-legacy-mach.c.
