cpu: Add a helper function cpu_get_lapic_addr
This change adds a helper function cpu_get_lapic_addr() that returns
LOCAL_APIC_ADDR for x86. It also adds a weak default implementation
which returns 0 if platform does not support LAPIC. This is being
done in preparation to move all ACPI table support in coreboot out of
arch/x86.
