Setting the `CONFIG_COMEDI_PCMCIA_DRIVERS` kernel configuration option
makes the main "comedi" module depend on the "pcmcia" module, but many
machines don't have PCMCIA slots and only a few low-level Comedi drivers
need PCMCIA support.  The Comedi PCMCIA support functions are all in
"comedi_pcmcia.c".  Turn it into a separate module so we don't have to
pull in the other PCMCIA support modules unnecessarily.

Some declarations and macro definitions in "comedidev.h" are protected
by various `#ifdef`s for kernel configuration options, but the header
file compiles fine without the `#ifdef`s regardless of whether those
config option macros are defined or not.  Remove the `#ifdef`s and
compile the affected code unconditionally.

Some low-level Comedi driver modules used to handle PCI devices and ISA
devices in the same module with some conditional compilation.  To reduce
the amount of conditional compilation, some dummy inline versions of
`comedi_to_pci_dev()`, `comedi_pci_enable()`, `comedi_pci_disable()`,
and `comedi_pci_detach()` are defined in "comedidev.h" if
`CONFIG_COMEDI_PCI_DRIVERS` is undefined.  Since those Comedi low-level
driver modules have since had PCI support split out into separate
modules, there is no need to keep the dummy inline functions around any
more, so remove them.
