This affects only a few sandbox tests which modify the device tree, but the number will grow as ofnode support for writing improves. While the control FDT is not intended to change while U-Boot is running, some tests do so. For example, the ofnode interface only supports modifying properties in the control FDT, so tests must use that. To solve this problem, keep a copy of the FDT and restore it as needed when the test is finished. The copy only happens on sandbox (except SPL builds), to reduce memory usage and because these tests are not useful on other boards. For other boards, a checksum is taken to ensure that nothing changes. It would be possible to always checksum the FDT on sandbox and only restore it if needed, but this is slightly slower than restoring it every time, at least with crc8. Move the code which checks for success to the very end, for clarity.

This is because only the node offset is encoded in ofnode, with the tree being implicit. This makes ofnode (without OF_LIVE) unsuitable for device tree fixups, as implemented by ft_board_setup() and other such functions. To solve this, we can use the top bits of the node offset to hold a tree ID. Add the definitions for this.

This works by using the top bits of ofnode.of_offset to encode a tree. It is assumed that there will only be a few device trees used at runtime, typically the control FDT (always tree ID 0) and possibly a separate FDT to be passed the OS. The maximum number of device trees supported at runtime is 8, with this implementation. That would use bits 30:28 of the node-offset value, meaning that the positive offset range is limited to bits 27:0, versus 30:1 with this feature disabled. That still allows a device tree of up to 256MB, which should be enough for most FITs. Larger ones can be supported by using external data with the FIT, or by enabling OF_LIVE.

This makes the API call a bit painful to use, since the caller must do different things depending on OF_LIVE. Add a new 'copy' argument which tells the function to make a copy if needed. Add some tests to cover this behaviour.
