There is no way to select BZIP2 compression method.

Changes from v1->v2:
1. Fix the issue if chosen node is not present.
Changes from previous version:
1. Renamed the DT node property to "boot-hartid" from "efi-boot-hartid".
2. Changed the property type to u32 instead of u64 for RV32 compatibility.
FU540 uses OF_SEPARATE instead of OF_PRIOR.
Enable OF_BOARD_FIXUP to update the DT with reserved-memory node.

The DT used by U-Boot may be different from the DT being passed to
the OS if the DT is loaded from external media such as network or
mmc. In that case, the reserved-memory node needs to be copied to
the DT passed to the OS.
