Until now there were two very similar functions allowing to get Linux IRQ number from ACPI handle (acpi_irq_get()) and OF node (of_irq_get()). The first one appeared to be used only as a subroutine of platform_irq_get(), which (in the generic code) limited IRQ obtaining from _CRS method only to nodes associated to kernel's struct platform_device. This patch introduces a new helper routine - fwnode_irq_get(), which allows to get the IRQ number directly from the fwnode to be used as common for OF/ACPI worlds. It is usable not only for the parents fwnodes, but also for the child nodes comprising their own _CRS methods with interrupts description. In order to be able o satisfy compilation with !CONFIG_ACPI and also simplify the new code, introduce a helper macro (ACPI_HANDLE_FWNODE), with which it is possible to reach an ACPI handle directly from its fwnode.
