Add 'fdt get size' test which works as follows: - Create fuller FDT, map it to sysmem - Get size of various properties - Get node count of available nodes - Test non-existent nodes and properties
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.
