e4a95d112e 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.

fbb0030e38 serial: struct serial_device: add uninit() entry for drivers 
Subsequent patch extends mpc512x serial driver to support
multiple PSC ports. The driver will provide an uninit()
function to stop the serial controller and to disable the
controller's clock. Adding uninit() entry to struct serial_device
allows disabling the serial controller after usage of
a stdio serial device.

This patch adds uninit() entry to the struct serial_device
and fixes initialization of this structure in the code
accordingly.

a47a12becf Move arch/ppc to arch/powerpc 
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
