One irqsteer channel can support up to 8 output interrupts.

ChangeLog:
v2->v3:
* add error check for imx_irqsteer_get_hwirq_base
* use DIV_ROUND_UP
* merge 'hwirq +=32' into for loop
* common error path in probe
Not all 64 interrupts may be used in one group. e.g. most irqsteer in
imx8qxp and imx8qm subsystems supports only 32 interrupts.
As the IP integration parameters are Channel number and interrupts number,
let's use fsl,irqs-num to represents how many interrupts supported
by this irqsteer channel.
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
Not all 64 interrupts may be used in one group. e.g. most irqsteer in

And one irqsteer channel can support up to 8 output interrupts.
This patch series aims to support 32 interrupts chan and multi output
interrupts.
Tested on:
iMX8QXP MEK
