UPSTREAM: Kconfig: Add config to insert ucode address in second FIT

This config is used to provide the name of a region where a microcode
is located. The address of this will be added as the first entry in
the FIT of the topswap bootblock.

This adds a capability to associate two microcodes for each
of the two bootblocks, this allows for the CPU to boot with different
microcodes with 2 separate bootblocks.
