rapidio: convert switch drivers to modules
Rework RapidIO switch drivers to add an option to build them as loadable kernel modules. This patch removes RapidIO-specific vmlinux section and converts switch drivers to be compatible with LDM driver registration method. To simplify registration of device-specific callback routines this patch introduces rio_switch_ops data structure. The sw_sysfs() callback is removed from the list of device-specific operations because under the new structure its functions can be handled by switch driver's probe() and remove() routines. If a specific switch device driver is not loaded the RapidIO subsystem core will use default standard-based operations to configure a switch. Because the current implementation of RapidIO enumeration/discovery method relies on availability of device-specific operations for error management, switch device drivers must be loaded before the RapidIO enumeration/discovery starts. This patch also moves several common routines from enumeration/discovery module into the RapidIO core code to make switch-specific operations accessible to all components of RapidIO subsystem.
