pcmcia : make PCMCIA depend on HAS_IOMEM

On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.

Here let depend PCMCIA on HAS_IOMEM so that it won't be built to
cause below compiling error if PCI is unset.

------
ld: drivers/pcmcia/cistpl.o: in function `set_cis_map':
cistpl.c:(.text+0x1202): undefined reference to `ioremap'

ld: drivers/pcmcia/cistpl.o: in function `release_cis_mem':

------

Besides, many other Kconfig option, e.g IPWIRELESS, PCMCIA_PCNET,
PCMCIA_FMVJ18X, PCMCIA_SMC91C92 which depends on PCMCIA also will
cause compiling error if enabled.

pcmcia: remove AT91RM9200 Compact Flash driver

As noted by Arnd Bergmann, "we used to have three drivers for the same
hardware (pcmcia, pata and ide), and only the pcmcia driver remained
in the tree after drivers/ide/ was removed and pata_at91 did not get
converted to DT". "There is no dts file in tree that actually declares
either of them, so chances are that nobody is actually using the CF
slot on at91 any more."[1]

On this rationale, remove the AT91RM9200 Compact Flash driver, which
also assists in reaching "the goal of stopping exporting OF-specific
APIs of gpiolib".[2]

pcmcia: Remove NEC VRC4173 CARDU

The driver was introduced in 2.6.11 in the pre-git times with commit
"[PATCH] mips: vR41xx updates". However, even back then, this driver
was not able to be compiled, as a number of udpates had been missing
from this driver: It still provided a "->get_io_map" callback (removed
for v2.5.66) and a "->inquire_socket" callback and used socket_cap_t
(removed for v2.5.72). Moreover, this driver failed to be brought and
be kept up to date; e.g. it still provides '->register_callback',
incompatible with a change committed for v2.6.14 in
commit 7f316b033b36 ("[PATCH] pcmcia: remove socket register_callback"),
and uses INIT_WORK() with three arguments which was removed in
commit 65f27f38446e1 ("WorkStruct: Pass the work_struct pointer instead
of context data")

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:
