It looks like it's ~4 years since we updated some of these, so do a bulk
update.
Verified that the before and after generated configs are exactly the
same.
Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

by 8 on Powerpc 8xx.
On PPC_8xx, CRC32_SLICEBY4 is more efficient (almost twice) than CRC32_SLICEBY8,
as shown below:
With CRC32_SLICEBY8:
[ 1.109204] crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64
[ 1.114401] crc32: self tests passed, processed 225944 bytes in 15118910 nsec
[ 1.130655] crc32c: CRC_LE_BITS = 64
[ 1.134235] crc32c: self tests passed, processed 225944 bytes in 4479879 nsec
With CRC32_SLICEBY4:
[ 1.097129] crc32: CRC_LE_BITS = 32, CRC_BE BITS = 32
[ 1.101878] crc32: self tests passed, processed 225944 bytes in 8616242 nsec
[ 1.116298] crc32c: CRC_LE_BITS = 32
[ 1.119607] crc32c: self tests passed, processed 225944 bytes in 3289576 nsec

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

a recent fc11 udev update on an 83xx board made root console login
disappear:
Updating : udev-141-8.fc11.ppc 32/83
udev: starting version 141
udev: deprecated sysfs layout; update the kernel or disable CONFIG_SYSFS_DEPRECATED;
some udev features will not work correctly
and sure enough, turning off SYSFS_DEPRECATED brings the login prompt back.

unset CONFIG_PCI_LEGACY in the defconfigs as none of them enable
ISDN drivers which seem to be the only place we are using pci_find_device

Since we are updated defconfigs I went ahead and moved the
asp8347_defconfig under 83xx/ and the mpc8536_ds_defconfig under
85xx/ as that is where they should have been to start with.

This updates all the defconfigs in arch/powerpc/configs except iseries
and ps3, which were updated by the preceding commits.
This mostly takes the defaults, except that I turned on tickless idle
and high-resolution timers for everything, and turned off instrumentation
support and "Fair group CPU scheduler" for the smaller/embedded platforms.

It now uses the new CPM binding and the generic pin/clock functions, and
has assorted fixes and cleanup.

This adds the core 8xx stuff and specifically mpc885ads board-specific
bits to arch/powerpc. Respective Kconfig has been cleaned up from the stuff
not yet ported over to avoid confusion. Updated and cleaned version.
