Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of
requiring manual settings of PCMCIA_DEBUG.

Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.

A few PCMCIA network drivers can make use of values provided by the pcmcia
core, instead of tedious, independent CIS parsing.

xirc32ps_cs.c: manf_id

hostap_cs.c: multifunction count

b43/pcmcia.c: ConfigBase address and "Present"

smc91c92_cs.c:  By default, mhz_setup() can use VERS_1 as it is stored
in struct pcmcia_device. Only some cards require workarounds, such as
reading out VERS_1 twice.

The driver version number has not been updated since the driver was
included in the main kernel tree and there is no plan on updating this
in the future either. At this point, the only correct way to refer to
the version is to use the kernel version. The 0.4.4 version is
confusing since there are external version with higher version number
even though they are not actually any newer than the in-tree version.

Let's get rid of the version number in the kernel tree in order to
avoid this kind of confusion.

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
        int (*resume)           (struct pcmcia_device *dev);
