Add 'fdt mknode' test which works as follows: - Create fuller FDT, map it to sysmem - Create node either in / or subnode - Attempt to create node over existing node, which fails - Attempt to create subnodes in non-existing nodes or aliases - Verify created nodes using fdt list command
The test case can be triggered using: " ./u-boot -Dc 'ut fdt' " To dump the full output from commands used during test, add '-v' flag.
