Now there are three small local headers. Some contain functions which are
only used in one source file.
Move all the inlines and declarations into a single local header and the
inlines which are only used in one source file into that.

The APIC ID as parsed from ACPI MADT is validity checked with the
apic->apic_id_valid() callback, which depends on the selected APIC type.
For non X2APIC types APIC IDs >= 0xFF are invalid, but values > 0x7FFFFFFF
are detected as valid. This happens because the 'apicid' argument of the
apic_id_valid() callback is type 'int'. So the resulting comparison
apicid < 0xFF
evaluates to true for all unsigned int values > 0x7FFFFFFF which are handed
to default_apic_id_valid(). As a consequence, invalid APIC IDs in !X2APIC
mode are considered valid and accounted as possible CPUs.
Change the apicid argument type of the apic_id_valid() callback to u32 so
the evaluation is unsigned and returns the correct result.

The set_apic_id() callback returns an unsigned long value which is handed
in to apic_write() as the value argument u32.
Adjust the return value so it returns u32 right away.

These inline functions are used in both the cluster and the physical x2apic
code to fill in the function pointers of the apic structure. That means the
code is generated twice for no reason.
Move it to a C code and reuse it.
