Add 'fdt header' test which works as follows: - Create basic FDT, map it to sysmem - Print the FDT header - Get all members of the FDT header into variable and verify the variables contain correct data
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.
