Mark's and Dzmitry's approaches come down to the same thing.. Let's unify them by first removing the static keyword from the common file to allow the variable to be reused, then renaming "reg0" to the more sensible fw_dtb_pointer coming from the Apple file and finally remove the mach-apple implementation of this very thing and enable the common approach in the respective defconfig.
