x86: queensbay: Change CPU_ADDR_BITS to 32
Per CPUID:80000008h result, the maximum physical address bits of TunnelCreek processor is 32 instead of default 36. This will fix the incorrect decoding of MTRR range mask. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
