The fixed number of 24 RTEs is a legacy thing, and long gone by now.
IOAPICs expose the maximum number of RTEs they have via the version
register, so let's use it.
This avoids to manually tweak a Kconfig option (which is now removed)
and fixes the RTE number for all x86 targets relevantly.

Pattern being <domain>_<model>.<c/h>.
Here interrupt_controller as a domain would be far too long so
shortening it to "intc", as DTS does actually.
