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.
