mfd: Fix max8925 irq control bit incorrect setting
In max8925_irq_sync_unlock(), irq control bit is set at the same time.
Zero means enabling irq, and one means disabling irq.
The original code is:
irq_chg[0] &= irq_data->enable;
It should be changed to:
irq_chg[0] &= ~irq_data->enable;
Otherwise, irq control bit is mess.
