[PATCH v2 0/5] RISC-V multi-socket support

[Anup Patel <anup.patel@wdc.com>]

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_v2 branch at:
https://github.com/avpatel/qemu.git

To try this patches, we will need: Linux multi-PLIC improvements
support which can be found in plic_imp_v2 branch at:
https://github.com/avpatel/linux.git

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
