irqchip/imx-intmux: Fix irqdata regs save in imx_intmux_runtime_suspend()
Gcc report warning as follows:
drivers/irqchip/irq-imx-intmux.c:316:29: warning:
variable 'irqchip_data' set but not used [-Wunused-but-set-variable]
316 | struct intmux_irqchip_data irqchip_data;
| ^~~~~~~~~~~~
irqdata regs is stored to this variable on the stack in
imx_intmux_runtime_suspend(), which means a nop. this commit
fix to save regs to the right place.
