FROMGIT: ASoC: Intel: sof_sdw: Avoid NULL check fail when re-probing

The static platform_component name string is overwritten on card tear
down by sof_link_unload(). After this has happened the NULL check
on it in asoc_sdw_init_simple_dai_link() will fail when the driver
is reprobed, causing the machine driver to fail probe. However, it
also turns out that the ASoC core sets this string for all topology
systems in soc_check_tplg_fes() anyway, after the aforementioned
NULL check. So there is no need for the machine driver to set
the platform name to anything meaningful at all.

Replace all the platform_component stuff with some simple place
holders and importantly since the core tampers with the
snd_soc_dai_link_component in multiple places allocate a new one
for each usage.
