Subject: [PATCH] powerpc/xmon: replace sizeof calculations with ARRAY_SIZE macro

The calculations for operand/opcode/macro numbers are done in an
identical manner to the already existing ARRAY_SIZE macro in
linux/array_size.h

This patch replaces the sizeof calculations with the macro to make the
code cleaner and more immediately obvious what it is doing.
