watchdog: sp5100_tco: Always use SP5100_IO_PM_{INDEX_REG,DATA_REG}
SP5100_IO_PM_INDEX_REG and SB800_IO_PM_INDEX_REG are used inconsistently and define the same value. Just use SP5100_IO_PM_INDEX_REG throughout. Do the same for SP5100_IO_PM_DATA_REG and SB800_IO_PM_DATA_REG. Use helper functions to access the indexed registers.
