cpu: Add microcode at pre-defined address

FSP-T takes microcode pointer and location parameters, and FSP-T is
invoked before CAR is setup and before memory is trained. So it is not
possible to modify supplied microcode pointer in runtime. Because of
that we have to hardcode the pointer in bootblock.

Also, on current version of FSP-T on Xeons microcode is not optional.
Reasons for that are currently unclear and are being investigated.

However for the present time we need to be able to add microcode at a
certain offset so FSP-T can be used

TEST=test on OCP TiogaPass board, as well as out-of-tree CPU/board
