x86: size NR_IRQS on 32-bit systems the same way as 64-bit

Impact: make NR_IRQS big enough for system with lots of apic/pins

If lots of IO_APIC's are there (or can be there), size the same way
as 64-bit, depending on MAX_IO_APICS and NR_CPUS.

This fixes the boot problem reported by Ben Hutchings on a 32-bit
server with 5 IO-APICs and 240 IO-APIC pins.
