Thomas Zimmermann bb610b6fc1 firmware: google: framebuffer: Do not mark framebuffer as busy 
commit f3850d399d upstream.

Remove the flag IORESOURCE_BUSY flag from coreboot's framebuffer
resource. It prevents simpledrm from successfully requesting the
range for its own use; resulting in errors such as

[    2.775430] simple-framebuffer simple-framebuffer.0: [drm] could not acquire memory region [mem 0x80000000-0x80407fff flags 0x80000200]

As with other uses of simple-framebuffer, the simple-framebuffer
device should only declare it's I/O resources, but not actively use
them.
