Input: cpcap-pwrbutton - remove initial kernel-doc notation

Change the beginning "/**" in the file to "/*" since it is not a
kernel-doc comment. This prevents a kernel-doc warning:

drivers/input/misc/cpcap-pwrbutton.c:2: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
