exynos4210_gic_realize() prints the number of cpus into some temporary
buffers, but it only allows 3 bytes space for it. That's plenty:
existing machines will only ever set this value to EXYNOS4210_NCPUS
(2). But the compiler can't always figure that out, so some[*] gcc9
versions emit -Wformat-truncation warnings.
We can fix that by hinting the constraint to the compiler with a
suitably placed assert().
[*] The bizarre thing here, is that I've long gotten these warnings
compiling in a 32-bit x86 container as host - Fedora 30 with
gcc-9.2.1-1.fc30.i686 - but it compiles just fine on my normal
x86_64 host - Fedora 30 with and gcc-9.2.1-1.fc30.x86_64.
