Merge patch series "riscv: CPU operations cleanup"

Samuel Holland <samuel.holland@sifive.com> says:

This series cleans up some duplicated and dead code around the RISC-V
CPU operations, that was copied from arm64 but is not needed here. The
result is a bit of memory savings and removal of a few SBI calls during
boot, with no functional change.

* b4-shazam-merge:
  riscv: Use the same CPU operations for all CPUs
  riscv: Remove unused members from struct cpu_operations
  riscv: Deduplicate code in setup_smp()
