pcmcia: use autoconfiguration feature for ioports and iomem

Browse Source 
When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding
fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
accordinly. Drivers wishing to override certain settings may do so in
the callback function, but they no longer need to parse the CIS entries
stored in cistpl_cftable_entry_t themselves.

This file details changes in 2.6 which affect PCMCIA card driver authors:
* pcmcia_loop_config() and autoconfiguration (as of 2.6.36)
If struct pcmcia_device *p_dev->config_flags is set accordingly,
pcmcia_loop_config() now sets up certain configuration values
automatically, though the driver may still override the settings
in the callback function. The following autoconfiguration options
are provided at the moment:
CONF_AUTO_CHECK_VCC : check for matching Vcc
CONF_AUTO_SET_VPP : set Vpp
CONF_AUTO_AUDIO : auto-enable audio line, if required
CONF_AUTO_SET_IO : set ioport resources (->resource[0,1])
CONF_AUTO_SET_IOMEM : set first iomem resource (->resource[2])
* pcmcia_request_configuration -> pcmcia_enable_device (as of 2.6.36)
pcmcia_request_configuration() got renamed to pcmcia_enable_device(),
as it mirrors pcmcia_disable_device(). Configuration settings are now
