drivercore: Generalize module_platform_driver
This patch generalizes the module_platform_driver macro and introduces a new module_driver macro. The module_driver macro takes a driver name, a register and a unregister function for this driver type. Using these it construct the module init and exit sections which register and unregister the driver. Since such init/exit sections are commonly found in drivers this macro can be used to eliminate a lot of boilerplate code. The macro is not intended to be used by driver modules directly, instead it should be used to generate bus specific macros for registering drivers like the module_platform_driver macro.
