ASoC: bengal: Fix euro usbc plug not detected during reboot

Euro usbc plug is not detected if we keep headset inserted
and reboot target. This is because usbc_swap_gnd_mic function
does not get called until mbhc interrupt is generated.
Implement late probe so that hs_detect is called after
sound card is registered.
