Calculate EMIF register values based on AC timing parameters from the SDRAM datasheet and the DDR frequency rather than using the hard-coded values.
For a new board the user doen't have to go through the tedious process of calculating the register values. Instead, just provide the AC timings from the device data sheet as input and the driver will automatically calculate the register values.

I get some warnings from arch/arm/cpu/armv7/omap4/emif.c: emif.c: In function ‘sdram_init’: emif.c:1164:43: warning: ‘section_map’ may be used uninitialized in this function emif.c:1166:27: warning: ‘lis_map_regs_calculated$dmm_lisa_map_3’ may be used uninitialized in this function emif.c: In function ‘sdram_init’: emif.c:1166:27: warning: ‘lis_map_regs_calculated$dmm_lisa_map_3’ may be used uninitialized in this function
Looking at the code I see that these are initialized but the compiler can't firgure that out.
