Move the detection of OF framebuffers from fbdev into of platform code and register a Linux platform device for each framebuffer. Allows for DRM-based OF drivers and real hot-unplugging of the framebuffer. This patchset has been tested with qemu's ppc64le emulation, which provides a framebuffer via OF display node. If someone has an older 32-bit system with BootX available, please test.
