serial: bcm283x_mu: make pending values more explicit dm_serial_ops.pending should return the number of characters, not just a valid C Boolean integer value. The existing code does already does this, but only as an accident since BCM283X_MU_LSR_RX_READY happens to be BIT(0). Enhance the code to be more explicit about the values it returns.
