dyn_array: don't break compiling for !CONFIG_SMP
Impact: build failure on uniprocessor
When compiling for !CONFIG_SMP, per_cpu_alloc_dyn_array() would fail
to compile, since it uses per_cpu_offset, which is not defined for
uniprocessor builds.
Hence, do not compile per_cpu_alloc_dyn_array() for !CONFIG_SMP.

Until now, NR_IRQS was derived from black magic defines that had to
be "large enough" to both accomodate NR_CPUS and MAX_NR_IO_APICs.
This resulted in a way too large irq_desc[] array on most x86 systems.
Especially with larger CPU masks, the size of irq_desc can spiral out
of control quickly.
So be smarter about it and use precise allocation instead: determine the
default maximum possible IRQ number from the ACPI MADT. Use a minimum limit
of at least 32 IRQs for broken BIOSes.
