atm: iphase: Fix set-but-not-used warnings.
The "iavcc" and "iadev" cases are obvious. The intr_status and frmr_intr cases are reading a register to clear the chip status. This driver is pretty old and creaky, and uses volatile pointer dereferences to do register I/O when it should be using readl() and friends. However that it outside of the scope of these changes.
