The AcpiMmioSel bit is the bit1 in AcpiMmioEn register, but, current sp5100_tco driver was using bit2.
The sp5100_tco driver expects zero as a value of AcpiMmioSel (bit1). fortunately, The problem didn't occur by this typo, because the default value of misused bit2 is zero. However, the sp5100_tco driver should use the correct bitmask value.
