[PATCH] arm/komeda: Compile komeda_debugfs_init() only if CONFIG_DEBUG_FS is enabled

[Liviu Dudau]

We don't call this function if CONFIG_DEBUG_FS is not defined, but we
should not be compiling it either, as the declaration of the debugfs
core functions is not included.

Reported by the kbuild test robot.
