gpio: davinci: move to platform device
Modify DaVinci GPIO driver to become a platform device driver. The driver does not have platform driver structure or a probe. Instead, it has pure_initcall function for initialization. The platform specific informaiton is obtained using the DaVinci specific davinci_soc_info structure. This is a problem for Device Tree (DT) implementation. As a first stage of DT conversion, we implement a probe. Additional notes: - The driver registration happens as postcore_initcall. This is required since machine init functions like da850_lcd_hw_init() make use of GPIO. - Start using devres APIs for simpler error handling.
