pcmcia: introduce autoconfiguration feature
Introduce an autoconfiguration feature to set certain values in
pcmcia_loop_config(), instead of copying the same code over and over
in each PCMCIA driver. At first, introduce the following options:
CONF_AUTO_CHECK_VCC check or matching Vcc entry
CONF_AUTO_SET_VPP set Vpp
CONF_AUTO_AUDIO enable the speaker line
