ARM: config: Refresh IXP4xx config after multiplatform

After converting to multiplatform the old IXP4xx defconfig
doesn't even activate the ethernet driver anymore, we need
to refresh this thoroughly.

- Drop options that ARCH_MULTI_V5 selects for us.
- Some options moved around because of multiplatform and
because generic Kconfig movements.
- Drop all MACH_* that do not exist anymore.
- Compress the kernel and initramfs with XZ as the memory
is often limited for these machines.
- Make sure IXP4XX_QMGR and IXP4XX_NPE is selected.
- Make sure the MTD_PHYSMAP_IXP4XX is selected and not
the old MTD_IXP4XX (will be deleted).
- Activate CRYPTO_DEV_IXP4XX
- Add some very basic default drivers such as AT24 EEPROMs
used in many routers.
- Add some kernel configs needed to bring up OpenWrt
which is the only userspace for these devices:
CGROUPS, DEVTMPFS, INOTIFY_USER, SIGNALFD, TIMERFD,
EPOLL, OVERLAY_FS and SQUASHFS.

ARM: ixp4xx: enable multiplatform support

After all the work that Linus Walleij did on this platform, it can be
part of a generic kernel build as well.

Note that there are known bugs in little-endian mode on ixp4xx, and
no other ARMv5 platform at this point supports big-endian mode, or is
likely to in the future, so there is limited practical value in this,
but it helps with build testing and ixp4xx little-endian support may
get fixed in the future.

net: wan: Delete the DLCI / SDLA drivers

The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).

The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).

The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.

(The WANPIPE driver was even once in the kernel, but was deleted in
commit 8db60bcf3021 ("[WAN]: Remove broken and unmaintained Sangoma
drivers.") because the vendor no longer updated the in-kernel WANPIPE
driver.)

arm: ixp4xx_defconfig: convert to use libata PATA drivers

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively. However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers. This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts ixp4xx_defconfig to use libata PATA
drivers.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

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.
