Add module parameter, IO mode autoprobe and PCMCIA reset code
required to support 100 Mbit PCMCIA ethernet cards on Amiga.
10 Mbit and 100 Mbit mode are supported by the same module.
Use the core PCMCIA cftable parser to detect 16 bit cards,
and automatically enable 16 bit ISA IO access for those cards
by changing isa_type at runtime. The user must select PCCARD
and PCMCIA in the kernel config to make the necessary support
modules available.
Code to reset the PCMCIA hardware required for 16 bit cards is
also added to the driver probe.
An optional module parameter switches Amiga ISA IO accessors
to 8 or 16 bit access in case autoprobe fails.
Patch modified after patch "[PATCH RFC net-next] Amiga PCMCIA
100 MBit card support" submitted to netdev 2018/09/16 by Alex
Kazik <alex@xxxxxxxx>.

Changes from v11:
Geert Uytterhoeven:
- use IS_REACHABLE() for PCMCIA dependent code
- use container_of() instead of cast in pcmcia_parse_tuple()
call
- set isa_type and apne_100_mbit correctly if autoprobe fails
- reset isa_type and apne_100_mbit on module exit
Joe Perches:
- use pr_debug and co. to avoid #ifdef DEBUG
Thanks for the update!

10 Mbit?
Sorry for reporting it only now. I had noticed in v11, but forgot to
mention it during my review.
For the code:
