Describe the bug
The MMIO address for the LOAPIC is still coming from CONFIG_LOAPIC_BASE_ADDRESS. We're not supposed to be obtaining HW addresses from Kconfig any more.
Even though this is a per-cpu peripheral that is part of the processor core itself, the base address of the LOAPIC in the memory map should be conveyed via dts like other drivers. It seems IOAPIC has DTS bindings but not LOAPIC, probably an omission.
I have no strong opinions on how the ontology for this should be set up, whether LOAPIC/IOAPIC merged into one "APIC" peripheral or maintained separately, etc.
