Revert "cpu/x86/mp_init.c: Set a bogus initial lapic_id"
This reverts commit 1bb9786da30e ("cpu/x86/mp_init.c: Set a bogus
initial lapic_id"), since it breaks MP init on amd/mandolin:
[INFO ] CPU #0 initialized
[INFO ] Initializing CPU #3
[INFO ] Initializing CPU #1
[INFO ] Initializing CPU #2
[EMERG] CPU: missing CPU device structureCPU: vendor AMD device 810f81
[DEBUG] CPU: family 17, model 18, stepping 01
[DEBUG] microcode: patch id to apply = 0x08108109
[INFO ] microcode: being updated to patch id = 0x08108109 succeeded
[INFO ] CPU #1 initialized
[ERROR] MP record 3 timeout.
[INFO ] bsp_do_flight_plan done after 1206 msecs.
[ERROR] MP initialization failure.
[EMERG] mp_init_with_smm failed. Halting.
