Add SM86_RTX3060_MOBILE tested config (975 MHz base clock, GA106)

[AndrewVu23]

Summary

Adds a tuned tested-config for the RTX 3060 Laptop (GA106, SM_86): 30 SM, 12 mem partitions, 3 MB L2, core clock 975 MHz (the base clock ncu profiles at), DP 64,64

Motivation / root cause

The core clock is set to 975 MHz , which is what the card actually runs at during ncu profiling (ncu --clock-control=base default), and also derived from gpc__cycles_elapsed_avg / gpu__time_duration after running different testsuites. Not the boost like in RTX 3070.

Changes

- configs/tested-cfgs/SM86_RTX3060_MOBILE/gpgpusim.config, config_ampere_islip.icnt

Test plan

• run_simulations.py -C RTX3060M-SASS completes on the ubench traces
• L2 math checks: 64×128×16×2×12 = 3 MB L2 = n_sets x line x assoc x n_sub x n_mem

Limitations / known gaps

WSL can't read memory/partition counts. That's why there are some configs that needed to be patched by hand:
-gpgpu_n_mem 12
-gpgpu_n_sub_partition_per_mchannel 2 SM_86 constant
-gpgpu_cache:dl2 S:64:128:16,L:B:m:L:P,A:192:4,32:0,32 RTX 3070 verbatim
-gpgpu_memory_partition_indexing 2 SM_86 constant
-icnt_flit_size SM_86 constant
-gpgpu_clock_domains 975:975:975:3000.5 measured + DRAM from RTX 3070
