boards: nxp: Fix usage of DT_CHOSEN() macro to get chosen Zephyr Flash

Used multiple places in the tree. The idea is to determine if this node
corresponds to a specific node (e.g: flexspi) so that specific
configurations can get done. Without the fix, the macro expansions were
defaulting to false.
