resource: Add I/O resource descriptor
walk_iomem_res() and region_intersects() still need to use strcmp() for searching a resource entry by @name in the iomem table. This patch introduces I/O resource descriptor 'desc' in struct resource for the iomem search interfaces. Drivers can assign their unique descriptor to a range when they support the search interfaces. Otherwise, 'desc' is set to IORES_DESC_NONE (0). This avoids changing most of the drivers as they typically allocate resource entries statically, or by calling alloc_resource(), kzalloc(), or alloc_bootmem_low(), which set the field to zero by default. A later patch will address some drivers that use kmalloc() without zero'ing the field. Also change release_mem_region_adjustable() to set 'desc' when its resource entry gets separated. Other resource interfaces are also changed to initialize 'desc' explicitly although alloc_resource() sets it to 0.
