Two config options exist to define powerpc MPC8xx:
* CONFIG_PPC_8xx
* CONFIG_8xx
In addition, CONFIG_PPC_8xx also defines CONFIG_CPM1 as
communication co-processor

arch/powerpc/platforms/Kconfig.cputype has contained the following
comment about CONFIG_8xx item for some years:
"# this is temp to handle compat with arch=ppc"

It looks like not many places still have that old CONFIG_8xx used,
so it is likely to be a good time to get rid of it completely ?

Patchset is composed of the following patches:
[1/8] powerpc: replace CONFIG_8xx by CONFIG_PPC_8xx
[2/8] um: replace CONFIG_8xx by CONFIG_PPC_8xx
[3/8] video: replace CONFIG_8xx by CONFIG_PPC_8xx
[4/8] net: freescale: replace CONFIG_8xx by CONFIG_PPC_8xx
[5/8] tty: cpm_uart: replace CONFIG_8xx by CONFIG_CPM1
[6/8] mtd: replace CONFIG_8xx by CONFIG_PPC_8xx
[7/8] isdn: replace CONFIG_8xx by CONFIG_PPC_8xx
[8/8] powerpc: get rid of CONFIG_8xx

All but the last one are independant and can be applied in any
order. Only the 8th one requires the first 7 patches to be applied.

We also have CONFIG_40x,. CONFIG_44x, and CONFIG_4xx.
There's no CONFIG_PPC_4* though.

Do we want (some) consistency?
