Subject: [PATCH v3 01/24] resource: Add DEFINE_RES_*_NAMED_FLAGS macro

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.
