[U-Boot] [PATCH v2 3/7] x86: baytrail: Support multiple microcode copies

From: Bin Meng <bmeng.cn at gmail.com>

Intel FSP has the capability to walk through the microcode blocks
which are passed as the TempRamInit() parameter from U-Boot and
finds the most appropriate microcode which is suitable for the cpu
on which it is running. Now we've seen several steppings for Intel
BayTrail series processors, adding those microcodes to the Intel
BayleyBay and MinnowMax board device tree files.

- Adjust to use separate nodes for each microcode block
