[PATCH v2] irqchip: imx-irqsteer: Convert to devm_pm_runtime_enable()

[Fabio Estevam <festevam@gmail.com>]

imx_irqsteer_probe() enables runtime PM, but imx_irqsteer_remove()
does not disable it.

Consequently, runtime PM remains enabled after unbinding the device,
and rebinding it triggers:

Unbalanced pm_runtime_enable!

Use devm_pm_runtime_enable() to automatically disable runtime PM when
the device is removed.

Fixes: 4730d2233311 ("irqchip/imx-irqsteer: Add runtime PM support")
