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.
