bsp/pc386: Update GDT to work for SMP
Create a GS segment in the GDT for each processor for storing TLS.
This makes the GDT in startAP.S obsolete as all processors now share the
same GDT, which is passed to each AP at startup.
The correct segment for each processor is calculated in cpu_asm.S.
Update #3335
