pcmcia: use pre-determined values 

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.
