[PATCH V3 3/4] irq: imx-irqsteer: change to use reg_num instead of irq_group

One group can manage 64 interrupts by using two registers (e.g. STATUS/SET). However, the integrated irqsteer may support only 32 interrupts which needs only one register in a group. But the current driver assume there's a mininum of two registers in a group which result in a wrong register map for

[PATCH V3 4/4] irq: imx: irqsteer: add multi output interrupts support
