Bin Meng f2653e8dd9 x86: coreboot: Control I/O port 0xb2 writing via device tree
Writing 0xcb to I/O port 0xb2 (Advanced Power Management Control) causes
U-Boot to hang on QEMU q35 target. We introduce a config option in the
device tree "u-boot,no-apm-finalize" under /config node if we don't want
to do that.
