sparc64: fix readout of cpu/fpu type

Meelis reported that on his box /proc/cpuinfo started
to reported "Unknow CPU" and the same did the boot messages.

It was a stupid bug I introduced when merging
cpu.c for 32 and 64 bit.

The code did an array reference where it had to search
for the right index.
