Add 'fdt resize' test which works as follows: - Create simple FDT with extra size 0, map it to sysmem - 'resize' the FDT by 0x2000 bytes - Verify the new space has been added to the FDT
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.
