ARM: 6168/1: ep93xx: move physmap flash registration into core.c
Create a core.c __init function to handle the physmap flash registration for all the ep93xx platforms. Also, modify all the ep93xx platforms to use this new function. This simplifies all the ep93xx platform init code and reduces the size of the kernel when including multiple ep93xx boards.
