fdt: send all dtc output to stderr
Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture the result code from dtc by echoing $? to stdout and capturing it using $(). However, dtc emits some diagnostics to stderr and some to stdout. The diagnostics send to stdout ended up getting captured via $() rather than being echo'd to the user. This caused those diagnostics to be passed to the exit command, which would then fail with the following cryptic error message: /bin/sh: line 1: exit: too many arguments Solve this by redirecting all dtc output to stderr so that $() does not capture it. This allows the user to see the actual error message from dtc.
