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.

w1_therm devices can either be bus powered or externally powered. When device is bus powered during temperature conversion the bus have to be left high to provide necessary power. Some masters also allow strong power-up to be enabled in this case. Naturally, no communication over bus can occur during that time. However, if device has external power then there is no such restriction, and host can talk to other devices during temperature conversion. There is command which allows us to check how device is powered, this patch uses it to release the bus on externally w1_therm powered devices during temperature conversion. Also, this changes uninterruptible sleeps there into interruptible ones to avoid long uninterruptible sleep if w1 subsystem happens to grab bus for scan during w1_therm_read().

Almost every platform_driver does the three steps get_resource, request_mem_region, ioremap. This does not only lead to a lot of code duplication, but also a huge number of similar error strings and inconsistent error codes on failure.
