[PATCH v2] DRM platform device support

Here is the second revision implementing platform device support for DRM. I've split the original patch into three and applied most of the comments I got from the previous go-around. The first patch removes the resource wrappers from DRM and switches the drivers to use the bus level functions. The second patch adds the platform support, and the third patch adds the ARM specific #ifdefs.

Plus, a bonus patch that ensures that the DRM offset fits into the pgoff (unsigned long) offset for mmap. The original code made a 64 bit value that didn't fly with a 32 bit processor.

Thanks for the comments and keep em coming.
