boards/nucleo-wl55jc: Set LOOPSPERMSEC=0 to avoid build errors

This board does not have a calibrated LOOPSPERMSEC value despite needing
one in order for correct operation. This commits sets the value to 0 so
that CI builds may pass, but users who build this board will see a
warning indicate the steps for calibrating a new value.
