ASoc: SOF: topology: Clear SOF link platform name upon unload
[ Upstream commit e0be875c5bf03a9676a6bfed9e0f1766922a7dbd ]
The SOF topology loading function sets the device name for the platform
component link. This should be unset when unloading the topology,
otherwise a machine driver unbind/bind or reprobe would complain about
an invalid component as having both its component name and of_node set:
mt8186_mt6366 sound: ASoC: Both Component name/of_node are set for AFE_SOF_DL1
mt8186_mt6366 sound: error -EINVAL: Cannot register card
mt8186_mt6366 sound: probe with driver mt8186_mt6366 failed with error -22
This happens with machine drivers that set the of_node separately.
Clear the SOF link platform name in the topology unload callback.
