powerpc: Allow the max stack trace depth to be configured
On my screen, when something crashes, I only have space for maybe 16 functions of the stack trace before the information above it scrolls off the screen. It's easy to hack the kernel to print out only that much, but it's harder to remember to do it. This introduces a config option for it so that I can keep the setting in my config.
