Summary

Commit 248f0ca converted intrcnt and intrnames from u_long[]
and char[] to u_long* and char* respectively, but for non-INTRNG mips
these symbols were defined in .S file as a pre-allocated static arrays,
so the problem wasn't cought at compile time. Conversion from an array
to a pointer requires pointer initialization and it wasn't done
for MIPS, so whatever happenned to be in the begginning of intcnt[]
array was used as a pointer value.

Move intrcnt/intrnames to C code and allocate them dynamically
although with a fixed size at the moment.

Test Plan

Tested on QEMU/MALTA64
