hw/riscv: Fix typo field in error_report

"smp.cpus" means the number of online CPUs and "smp.max_cpus" means the
total number of CPUs.

riscv_numa_get_default_cpu_node_id() checks "smp.cpus" and the
"available CPUs" description in the next error message also indicates
online CPUs.

So report "smp.cpus" in error_report() instand of "smp.max_cpus".

Since "smp.cpus" is "unsigned int", use "%u".

Merge remote-tracking branch 'remotes/alistair/tags/pull-riscv-to-apply-20200825' into staging

This pull request first adds support for multi-socket NUMA RISC-V
machines. The Spike and Virt machines both support NUMA sockets.

This PR also updates the current experimental Hypervisor support to the
v0.6.1 spec.

hw/riscv: Add helpers for RISC-V multi-socket NUMA machines

We add common helper routines which can be shared by RISC-V
multi-socket NUMA machines.

We have two types of helpers:
1. riscv_socket_xyz

hw/riscv: Add helpers for RISC-V multi-socket NUMA machines

We add common helper routines which can be shared by RISC-V
multi-socket NUMA machines.

We have two types of helpers:
1. riscv_socket_xyz() - These helper assist managing multiple
sockets irrespective whether QEMU NUMA is enabled/disabled
2. riscv_numa_xyz() - These helpers assist in providing
necessary QEMU machine callbacks for QEMU NUMA emulation
