cpu/x86/mp_init.c: Set topology on BSP
The BSP might have non-zero lapicid so set the topology accordingly,
without assuming it is 0. This fixes a cpu exception on at least Intel
Meteorlake. This was caused by FSP CPU PPI being giving incorrect
information about the BSP topology.
This problem was introduced by 8b8400a "drivers/fsp2_0/mp_service_ppi:
Use struct device to fill in buffer" which sets the PPI struct based on
struct device.
