kernel: drop PCFG poison experiment and config-write spam, keep bus-info detail log
The poison test (fill every dword of BAR0 0x88000-0x88FFF, 0xB80000-
0xB80EFF, 0xC08000-0xC08EFF with 0x103) did not change the CUDA "Unknown
PCIe speed" failure, proving the failing BUS_GET_INFO_V2 index-3 data does
not come from any BAR0 mirror read. Combined with the QEMU config-space
behavior (link registers zeroed, type=0x92, 0x84 never read from us) the
value must come from the VGPU_STATIC_INFO branch in getBusInfos (pVSI->
pcieGpuLinkCaps), i.e. the guest needs the host vGPU static-info payload.
Cleanup: remove the poison loops and the per-write CFGWR log; keep the
once-per-init PCIe cap print and add per-entry BUS_GET_INFO_V2 logging
(index+data) for the ongoing CUDA/UVM work.
