[PATCH RFC 03/11] driver core: platform: Add static ACPI nodes IRQ retrieval/mapping code

[Lorenzo Pieralisi <lpieralisi@kernel.org>]

ACPI static fwnodes types are not contemplated in the current

platform_get_irq_affinity()

implementation that is there to retrieve and map IRQs for a device.

Add fwnode_irq_get() to platform_get_irq_affinity() for static ACPI fwnodes
to overcome this shortcoming, enabling IRQ retrieval and mapping for the
ACPI static fwnode type.
