move pi3usb9201.h to driver/bc12/

Currently pi3usb9281's header and implementation lives in different
folder, header is in driver/usb_mux/, but implementation is in
driver/bc12/. From the git log of these two files, this looks
unintended.

This CL moves header file into driver/bc12/ for consistency. Nothing
else need to be changed since all references to this header does not
hard-code its path.

BUG=none
TEST=make buildall
BRANCH=none
