drm: Make drm_local_map use a resource_size_t offset
This changes drm_local_map to use a resource_size for its "offset" member instead of an unsigned long, thus allowing 32-bit machines with a >32-bit physical address space to be able to store there their register or framebuffer addresses when those are above 4G, such as when using a PCI video card on a recent AMCC 440 SoC. This patch isn't as "trivial" as it sounds: A few functions needed to have some unsigned long/int changed to resource_size_t and a few printk's had to be adjusted. But also, because userspace isn't capable of passing such offsets, I had to modify drm_find_matching_map() to ignore the offset passed in for maps of type _DRM_FRAMEBUFFER or _DRM_REGISTERS. If we ever support multiple _DRM_FRAMEBUFFER or _DRM_REGISTERS maps for a given device, we might have to change that trick, but I don't think that happens on any current driver.
