Subject: [PATCH v2 15/16] property: Drop functions operating on "available" child nodes

fwnode_get_next_available_child_node() and later
fwnode_for_each_available_child_node() were introduced to mirror the OF
interface operating on OF nodes. Now that these two are functionally the
same as the variants without "_available" part, drop the "_available"
variants.
