powerpc: Consolidate bootcount_{store|load} for PowerPC
This patch consolidates bootcount_{store|load} for PowerPC by implementing a common version in arch/powerpc/lib/bootcount.c. This code is now used by all PowerPC variants that currently have these functions implemented. The functions now use the proper IO-accessor functions to read/write the values. This code also supports two different bootcount versions: a) Use 2 separate words (2 * 32bit) to store the bootcounter b) Use only 1 word (2 * 16bit) to store the bootcounter Version b) was already used by MPC5xxx.
