Subject: [PATCH] interconnect: fix build warning without DEBUGFS

The icc_debugfs_dir variable is only used inside of an #ifdef
and should be moved into the same to avoid a harmless warning:

drivers/interconnect/core.c:26:23: error: 'icc_debugfs_dir' defined but not used [-Werror=unused-variable]

Fixes: d54599e06b06 ("interconnect: Allow endpoints translation via DT")
