mci: Add card_present callback ...

Currently there is no common way for the mci host driver to tell
that there is no card present. This adds a card_present callback
which is used by the framework to tell whether it's present or not.

of: rename new_device_node to of_new_node and export it ...

of_new_node now takes the parent node and the name as argument and
creates a new node. This simplifies the caller and also makes the
function useful for others, so export it.

of: of_free fixes ...

- Add missing prototype for of_free()

- (re)scan aliases after freeing a node. This is necessary because
  the freed node may be an alias or point to an alias

of: make of_get_fixed_tree more universally usable ...

Currently the bootm code uses of_fix_tree to apply the fixups
to the devicetree given on the command line. This function assumes
that there is enough space for the fixups available. Also on ARM
we have to make sure the tree does not cross 1Mib boundaries.

This patch moves the space allocation and alignment ensurance
to of_get_fixed_tree and uses it in bootm. This is the first
step for making of_get_fixed_tree the single point of devicetree
handling in barebox.
of_get_fixed_tree now takes an argument of the input fdt. If it is
given, this one is used, otherwise an internal oftree is used which
will be created in subsequent patches.
