usb: typec: wcove: Fx wrong kernel doc format

The top comment in the file wrongly uses kernel doc format:

.../typec/tcpm/wcove.c:17: warning: expecting prototype for typec_wcove.c - WhiskeyCove PMIC USB Type(). Prototype was for WCOVE_CHGRIRQ0() instead

Fix this by converting it to plain comment.

Fixes: ae8a2ca8 ("usb: typec: Group all TCPCI/TCPM code together")
