[PATCH v5 9/9] irqchip/imx-irqsteer: Use devm_irq_domain_create_linear()

[Zhipeng.wang_1 at oss.nxp.com]

From: Zhipeng Wang <zhipeng.wang_1 at nxp.com>

The driver open-codes an irq_domain_info and calls
devm_irq_domain_instantiate() only to get a linear revmap domain tied to
the device lifetime. Use the new devm_irq_domain_create_linear() helper
instead. No functional change.
