From: KV Sujith <sujit...@ti.com>
DaVinci GPIO driver now uses platform device model.
Convert DA8XX SoC code to use the new model.
- Add Memory and IRQ resources for da8xx
- Add da8xx_register_gpio API to create platform device for da8xx
platforms.
- Removed unused GPIO initialization in davinci_soc_info structure
