A number of the peripherals for the ep93xx are registered at startup using platform_data that is passed from the board init code to the core code. This data is then copied to a local static variable in the core code. Since the data is copied, the original data can be marked as __initdata and discarded after startup is complete. This adds the __initdata tag to all the appropriate data in the various ep93xx board init's. Specifically, all the struct ep93xx_eth_data, struct ep93xxfb_mach_info, and struct i2c_gpio_platform_data. Also, document the various registration functions and note what data should be marked as __initdata. While here, also cleanup a couple over zealous whitespace tabs.
