Revert "firmware: tegra: bpmp: Use scoped device node handling to simplify error paths"

Browse Source 
This reverts commit 8812b8689e ("firmware: tegra: bpmp: Use scoped
device node handling to simplify error paths") because it was silently
modified by committer during commit process, by moving declaration of
'struct device_node *np' above the initializer/constructor.  Such code
was not intention of the author, is not conforming to cleanup.h code
style and decreases the code readability.

I did not write such code and I did not agree to put my name with such
commit.
