Create IOAPIC and LOAPIC Kconfig options

Browse source 
Creating the IOAPIC and LOAPIC Kconfig options permits future commits to remove
those settings from the relevant board.h files.

help
This option indicates the maximum number of Redirection Table Entries
(RTEs) (one per IRQ available to the IO-APIC) made available to the
kernel, regardless of the number provided by the hardware itself. For
most efficient usage of memory, it should match the number of IRQ lines
needed by devices connected to the IO-APIC.
