Add Kconfig option, module parameter 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. A module parameter switches Amiga ISA IO accessors to word access by changing isa_type at runtime. Additional code to reset the PCMCIA hardware is also added to the driver probe. 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>.
