f73659192b 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 because the vendor no longer updated the in-kernel WANPIPE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.)

f8ae7bbec7 net: x25_asy: Delete the x25_asy driver
This driver transports LAPB (X.25 link layer) frames over TTY links.

I can safely say that this driver has no actual user because it was
not working at all until:
commit 8fdcabeac398 ("drivers/net/wan/x25_asy: Fix to make it work")

The code in its current state still has problems:

1.
The uses of "struct x25_asy" in x25_asy_unesc (when receiving) and in
x25_asy_write_wakeup (when sending) are not protected by locks against
x25_asy_change_mtu's changing of the transmitting/receiving buffers.
Also, all "netif_running" checks in this driver are not protected by
locks against the ndo_stop function.

2.
The driver stops all TTY read/write when the netif is down.
I think this is not right because this may cause the last outgoing frame
before the netif goes down to be incompletely transmitted, and the first
incoming frame after the netif goes up to be incompletely received.

And there may also be other problems.

I was planning to fix these problems but after recent discussions about
deleting other old networking code, I think we may just delete this
driver, too.

e223a4cca7 MIPS: Alchemy: use the OHCI platform driver
Convert the Alchemy platform to register the ohci-platform driver, now that
the ohci-platform driver properly handles the specific ohci-au1xxx resume
from suspend case.

This also greatly simplifies the power_{on,off} callbacks and make them
work on platform device id instead of checking the OHCI controller base
address like what was done in ohci-au1xxx.c.

Impacted defconfigs are also updated accordingly to select the OHCI platform
driver.

6a108a14fa 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.
