wifi: remove orphaned orinoco driver

Orinoco is a PIO-only ISA/PCMCIA 802.11b device with extra bus interface
connections for PCI/Cardbus/mini-PCI and a few pre-2002 Apple PowerMac
variants. It supports both wireless extensions and CFG80211, but I could
not tell if it requires using both.

This device used to be one of the most common ones 20 years ago, but
has been orphaned for most of the time since then, and the conversion
to cfg80211 has stalled in 2010.

wifi: remove obsolete hostap driver

HostAP is an ISA/PCMCIA style 802.11b driver supporting only
wireless extensions, and some custom ioctls (already removed).
Some devices include a legacy PCI bridge but no DMA.

The driver was marked obsolete in 2016 and is highly unlikely
to still have any users.

intersil: remove obsolete prism54 wireless driver

Commit 1d89cae1b47d ("MAINTAINERS: mark prism54 obsolete") indicated the
prism54 driver as obsolete in July 2010.

Now, after being exposed for ten years to refactoring, general tree-wide
changes and various janitor clean-up, it is really time to delete the
driver for good.

This was discovered as part of a checkpatch evaluation, investigating all
reports of checkpatch's WARNING:OBSOLETE check.

p54 replaces prism54 so users should be unaffected. There was a one off chipset
someone long ago reported that p54 didn't work with but the reporter never
followed up on that. Additionally, distributions have been blacklisting prism54
for years now.

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/'

net/wireless: fix spaces and grammar copy/paste in vendor Kconfig help text

Lots of the wireless driver vendor Kconfig symol help text says
"questions about cards." (2 spaces between "about" and "cards")

Besides dropping one of those spaces, it also needs some other word
inserted there. Instead of putting each vendor's name there, I chose
to say "these" cards in all of the Kconfig help text.
