x86: io-apic: IO-APIC MMIO should not fail on resource insertion
If IO-APIC base address is 1K aligned we should not fail
on resourse insertion procedure. For this sake we define
IO_APIC_SLOT_SIZE constant which should cover all IO-APIC
direct accessible registers.
An example of a such configuration is there
