[PATCH] RISC-V: Show CPU ID and Hart ID separately in /proc/cpuinfo

[Anup Patel]

Currently, /proc/cpuinfo show logical CPU ID as Hart ID which
is in-correct. This patch shows CPU ID and Hart ID separately
in /proc/cpuinfo using cpuid_to_hardid_map().

With this patch, contents of /proc/cpuinfo looks as follows:
cpu     : 0
hart    : 1
isa     : rv64imafdcsu
mmu     : sv48

cpu     : 1
hart    : 0
isa     : rv64imafdcsu
mmu     : sv48

cpu     : 2
hart    : 3
isa     : rv64imafdcsu
mmu     : sv48

cpu     : 3
hart    : 2
isa     : rv64imafdcsu
mmu     : sv48
