ARM: 5992/1: ep93xx: pass platform startup data as __initdata
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.
