Hartley Sweeten a2bd40d215 [ARM] 5504/1: ep93xx: Merge all edb93xx platforms 
The Cirrus Logic EDB93xx development board platform init files
share redundant code. The only differences are in the flash
memory configuration, MACH_TYPE, and additional on-board
I2C devices. This patch merges all of them into one file.
