[v6,0/5] RISC-V multi-socket support

Message

This series adds multi-socket support for RISC-V virt machine and
RISC-V spike machine. The multi-socket support will help us improve
various RISC-V operating systems, firmwares, and bootloader to
support RISC-V NUMA systems.

These patch can be found in riscv_multi_socket_v6 branch at:
https://github.com/avpatel/qemu.git

Changes since v5:
 - Rebased patches on Spike changes from Alistair
 - Added comments describing RISC-V NUMA helper functions

Changes since v4:
 - Re-arrange patches and move CLINT and PLIC patches before other
   patches because these are already reviewed
 - Added PATCH3 for common RISC-V multi-socket helpers
 - Added support for "-numa cpu,node-id" option in PATCH4 and PATCH5

Changes since v3:
 - Use "-numa" QEMU options to populate sockets instead of custom
   "multi-socket" sub-option in machine name

Changes since v2:
 - Dropped PATCH1 as it is not required any more
 - Added "multi-socket" sub-option for Spike and Virt machine
   which can be used to enable/disable mult-socket support

Changes since v1:
 - Fixed checkpatch errors and warnings
 - Added PATCH1 for knowning whether "sockets" sub-option was specified
 - Remove SPIKE_CPUS_PER_SOCKET_MIN and SPIKE_CPUS_PER_SOCKET_MAX in PATCH3
 - Remove VIRT_CPUS_PER_SOCKET_MIN and VIRT_CPUS_PER_SOCKET_MAX in PATCH5
