net: handle HAS_IOPORT dependencies

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for
those drivers requiring them. For the DEFXX driver the use of I/O
ports is optional and we only need to fence specific code paths. It also
turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need
the !S390 dependency and successfully builds the bpqether driver.

There are very few ISA drivers left that rely on the static probing from
drivers/net/Space.o. Make them all select a new CONFIG_NETDEV_LEGACY_INIT
symbol, and drop the entire probe logic when that is disabled.

The 9 drivers that are called from Space.c are the same set that
calls netdev_boot_setup_check().

docs: networking: reorganize driver documentation again

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.

While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.

treewide: replace '---help---' in Kconfig files with 'help'

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

drivers/net: remove all references to obsolete Ethernet-HOWTO

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.

However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.

No code is changed in this commit, just Kconfig help text.

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP

If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally. So
HAS_IOPORT_MAP is the better name for this.

Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available. I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.

The changes in this commit were done using:

$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

drivers/net: delete old 8bit ISA 3c501 driver.

It was amusing that linux was able to make use of this 1980's
technology on machines long past its intended lifespan, but
it probably should go now.

To set some context, the 3c501 was designed in the 1980's to be
used on 8088 PC-XT 8bit ISA machines. It was built using a large
number of discrete TTL components and truly looks like a relic
of the ancient past before large scale integration was common.

But from a functional point of view, the real issue, as stated
in the (also obsolete) Ethernet-HowTo, is that "...the 3c501 can
only do one thing at a time -- while you are removing one packet
from the single-packet buffer it cannot receive another packet,
nor can it receive a packet while loading a transmit packet."

You know things are not good when the Kconfig help text suggests
you make a cron job doing a ping every minute.

Hardware that old and crippled is simply not going to be used by
anyone in a time where 10 year old 100Mbit PCI cards (that are
still functional) are largely give-away items.
