arm: am57xx: env: Fix DFU variables

Commit 8502fe84a4fc ("configs: am57xx_evm: define
CONFIG_SPL_LOAD_FIT_ADDRESS for SPL-DFU") implements incorrect ifdef
logic, which leads to DFU variables absence in non-SPL environment. Fix
that in order to bring back DFU variables, by reflecting the logic in
include/configs/dra7xx_evm.h.
