test: cmd: fdt: Test fdt rm

Browse source 
Add 'fdt rm' test which works as follows:
- Create fuller FDT, map it to sysmem
- Selectively delete nodes or properties by both path and aliases
- Verify created nodes or properties using fdt print command

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.
