riscv: dts: starfive: Add JH7100 CPU topology
Add cpu-map binding to inform the kernel about the hardware topology
of the CPU cores.
Before this change, lstopo would report 1 core with 2 threads:
Machine (7231MB total)
Package L#0
NUMANode L#0 (P#0 7231MB)
L2 L#0 (2048KB) + Core L#0
L1d L#0 (32KB) + L1i L#0 (32KB) + PU L#0 (P#0)
L1d L#1 (32KB) + L1i L#1 (32KB) + PU L#1 (P#1)
After this change, it correctly identifies two cores:
Machine (7231MB total)
Package L#0
NUMANode L#0 (P#0 7231MB)
L2 L#0 (2048KB)
L1d L#0 (32KB) + L1i L#0 (32KB) + Core L#0 + PU L#0 (P#0)
L1d L#1 (32KB) + L1i L#1 (32KB) + Core L#1 + PU L#1 (P#1)
