libfdt: Add functions for handling the "compatible" property

Browse source 
This patch adds functions for dealing with the compatible property.
fdt_node_check_compatible() can be used to determine whether a node is
compatible with a given string and fdt_node_offset_by_compatible()
locates nodes with a given compatible string.

Testcases for these functions are also included.
