test: cmd: fdt: Test fdt apply
Add 'fdt chosen' test which works as follows: - Create basic DT, map it to sysmem - Apply DTO which adds single property via fragment (without address spec) - Apply DTO which adds more properties (string, u32, empty) and a subnode, with phandle via frament@0 and thus tests /__symbols__ node - Apply DTO which modifies property of the previous DTO via phandle and thus tests the /__fixups__ node - Print modified DT, verify it contains updates from DTOs 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.
