[PATCH] x86/Kconfig: simplify X86_IO_APIC dependencies

["Jan Beulich" <JBeulich@suse.com>]

Since dependencies are transitive, we don't really need to repeat those
of X86_UP_IOAPIC.

Furthermore avoid the symbol getting entered into .config when it is
off by having the default simply Y and the dependencies solely handled
via the intended for that purpose "depends on".
