mtd: nand: davinci: don't request AEMIF address range
The TI AEMIF driver registers are used to setup timings for each chip select. The same registers range is used to setup NAND settings. The AEMIF and NAND drivers not use the same registers in this range. In case with TI AEMIF driver, the memory address range is requested already by AEMIF, so we cannot request it twice, just ioremap.
