Ruslan Bukin b803d0b790 Add support for HiFive Unleashed -- the board with a multi-core RISC-V SoC
from SiFive, Inc.

The first core on this SoC (hart 0) is a 64-bit microcontroller.

o Pick a hart to run boot process using hart lottery.
  This allows to exclude hart 0 from running the boot process.
  (BBL releases hart 0 after the main harts, so it never wins the lottery).
o Renumber CPUs early on boot.
  Exclude non-MMU cores. Store the original hart ID in struct pcpu. This
  allows to find out the correct destination for IPIs and remote sfence
  calls.

Thanks to SiFive, Inc for the board provided.
