[PATCH 15/18] Add initrd information to the device tree in ft_finalize().

[Scott Wood]

linux,initrd-start and linux,initrd-end are added to the device tree
based on the values that platform code puts in the initrd struct.
ft_finalize() is also made global, so that platform code can do further
manipulation before returning to generic code.
