This just adds in another field of what's stored in the e-fuse on rk3288. Though I can't personally promise that every rk3288 out there has the CPU ID stored in the eFuse at this location, there is some evidence that it is correct: - This matches what was in the Chrome OS 3.14 branch (see EFUSE_CHIP_UID_OFFSET and EFUSE_CHIP_UID_LEN) for rk3288. - The upstream rk3399 dts file has this same data at the same offset and with the same length, indiciating that this is likely common for several modern Rockchip SoCs.
