Subject: [PATCH v3 0/5] cdx: provide sysfs interface for cdx device resources

- reset all the devices on cdx bus
- subsystem, class and revision for cdx device
Changes in v3:
- Remove local cdx controller list from cdx bus system and
instead use platform bus to locate controller

- Split sysfs entry enable to enable and disable
- sysfs entry enable and disable take bus number as an argument
- sysfs entry reset takes bus number as an argument
