Looks like this is being added only to satisfy the devm_clk_get() call
in nand_davinci_probe() which I think is superfluous since we also
enable the same clock in aemif_probe().

Perhaps the better solution is to drip the clk code in
drivers/mtd/nand/davinci_nand.c and shift legacy code to start using
drivers/memory/aemif.c as well? This way we can also drop
arch/arm/mach-davinci/aemif.c

Thanks,
