Add 'fdt bootcpu' test which works as follows: - Create basic FDT, map it to sysmem - Print the FDT bootcpu - Set the FDT bootcpu and read the value back using 'fdt header get' - Perform the previous step twice to validate bootcpu overwrite
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.
