Support reading the "interrupts" property from the devicetree in case the "interrupts-extended" property isn't found. As the "interrupts" property is commonly used, this allows to parse all existing FDT and makes irq_get_by_index() more useful. The "interrupts" property doesn't contain a phandle as "interrupts-extended" does, so implement a new method to locate the interrupt-parent called irq_get_interrupt_parent(). TEST: Read the interrupts from the GIC node for ACPI MADT generation. Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reviewed-by: Moritz Fischer <moritzf@google.com>
