[Freedreno] [PATCH libdrm] freedreno: add dummy fd_bo_from_fbdev implementation when KGSL is disabled

[Nicolas Dechesne]

Make sure that this function is defined (even empty/dummy) when KGSL support is
disabled, since it's part of the driver i/f and it was reported to cause symbols
issues when building against musl libc implementation.
