Revert "src/arch/x86: Use core apic id to get cpu_index()"
This reverts commit 095c931cf12924da9011b47aa64f4a6f11d89f13.
Previously cpu_info() was implemented with a struct on top of an
aligned stack. As FSP changed the stack value cpu_info() could not be
used in FSP context (which PPI is). Now cpu_info() uses GDT segments,
which FSP does not touch so it can be used.
This also exports cpu_infos from cpu.c as it's a convenient way to get
the struct device * for a certain index.
TESTED on aldrvp: FSP-S works and is able to run code on APs.
