powerpc has a variable number of PTRS_PER_*, set at runtime based on the MMU that the kernel is booted under. This means the PTRS_PER_* are no longer constants, and therefore breaks the build. Define default MAX_PTRS_PER_*s in the same style as MAX_PTRS_PER_P4D. As KASAN is the only user at the moment, just define them in the kasan header, and have them default to PTRS_PER_* unless overridden in arch code.
