Filip Lewiński 95461ee3df Documentation/soc/intel/redundancy.md: add
Add documentation for the Intel PCH Top Swap based A/B redundancy
mechanism. Describe the BOOTBLOCK and TOPSWAP bootblock regions,
COREBOOT and COREBOOT_TS CBFS regions, the attempt_slot_b CMOS option
and its application time, and how the active CBFS region is selected
based on the Top Swap state.

This follows the A/B redundancy proposal discussed on the coreboot
mailing list:
