Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ------------------------------------------------------------------------
Add a common function to set the fields for a irq resource to disabled, which mimics what is done in acpi_dev_irqresource_disabled(), with a view to replace that function.
