random: deobfuscate irq u32/u64 contributions
commit b2f408f upstream. In the irq handler, we fill out 16 bytes differently on 32-bit and 64-bit platforms, and for 32-bit vs 64-bit cycle counters, which doesn't always correspond with the bitness of the platform. Whether or not you like this strangeness, it is a matter of fact. But it might not be a fact you well realized until now, because the code that loaded the irq info into 4 32-bit words was quite confusing. Instead, this commit makes everything explicit by having separate (compile-time) branches for 32-bit and 64-bit types.
