Tejun Heo acb8bc09c6 x86: Add apic->x86_32_early_logical_apicid()
On x86_32, the mapping between cpu and logical apic ID differs
depending on the specific apic implementation in use.  The
mapping is initialized while bringing up CPUs; however, this
makes early inits ignore memory topology.

Add a x86_32 specific apic->x86_32_early_logical_apicid() which
is called early during boot to query the mapping.  The mapping
is later verified against the result of init_apic_ldr().  The
method is allowed to return BAD_APICID if it can't be determined
early.

noop variant which always returns BAD_APICID is implemented and
added to all x86_32 apic implementations.
