Subject: [PATCH] usb: dwc3: imx8mp: fix incorrect kernel-doc comment syntax

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/usb/dwc3/dwc3-imx8mp.c follows this syntax, but the
content inside does not comply with kernel-doc.

This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc:
"warning: expecting prototype for dwc3(). Prototype was for USB_WAKEUP_CTRL() instead"

Provide a simple fix by replacing this occurrence with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.
