x86: crownbay: Add MP initialization
Intel Crown Bay board has a TunnelCreek processor which supports hyper-threading. Add /cpus node in the crownbay.dts and enable the MP initialization. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (modified to remove error: overriding the value of OF_CONTROL. Old value: "y", new value: "y")
