  In some cases, it would be nice to instantiate a struct resource with
custom flags. For example, creating an IRQ resource with a flag that
marks the interrupt as wake capable.

Add a set of macros to provide custom flag arguments.

Was it @intel.com? Please, use @linux.intel.com anyway.

Tag block must _not_ have any blank line(s).

Otherwise LGTM,

While we will have user only for IRQ case, the rest are added for symmetry's
sake, I think it's okay and we might even have more (existing) users to convert
to new macros (at least it rings a bell to me for a few places).
