Either:
(a) we looked at the documentation for the hardware, which told us
that this SoC is built with its Cortex-M core configured with
that many interrupt lines

Or:
(b) this is for legacy reasons a bogus setting which happens to
work because it's too big rather than too small

For a new SoC, you need to follow course (a), ie look at what
the hardware is and model that.
