hush: Add extra define for hush debugging
I've seen people increasing the compile loglevel to get more debugging output from barebox. This is generally a good idea, but the tons of hush debugging printed makes barebox quite unusable. This patch puts hush debugging behind an extra HUSH_DEBUG define so increasing the compile loglevel no longer results in hush debugging. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
