sound:simple card: fix cannot register pwmdac and hdmi snd card

Browse source 
in soc_check_tplg_fes func, traverse all components for current card to
decide if we should modify dai-link params and use topology(the source
dai-link params is get from dts). because the sof-dsp component is in
the global components list, the sof-dsp set the ignore_machine as the
"asoc simple card", the ignore_machine matches the pwmdac
card->dev->driver->name, so the dai-link params is modified.
But in actually, the pwmdac and hdmi snd card should not use topology
and the dai-link should not be modified. we use no_plat vairalbe in
dai_link to indicates there is no platform component in dai-link and no
sof-dsp plat, and we dont use topology and dont need to change dai-link
params.
