ASoC: Intel: rename shadowed variable for all broadwell boards

Fix cppcheck warnings:

sound/soc/intel/boards/bdw-rt5650.c:91:23: style: Local variable
'channels' shadows outer variable [shadowVariable]

sound/soc/intel/boards/bdw-rt5677.c:144:23: style: Local variable
'channels' shadows outer variable [shadowVariable]

sound/soc/intel/boards/broadwell.c:91:23: style: Local variable
'channels' shadows outer variable [shadowVariable]

This was fixed earlier in other machine drivers but keeps coming back
with copy/paste.
