Bharat Nihalani 354ef0dbe0 drivers: Use runtime debugfs check ...

When kernel command line debugfs=off is specified instead of
disabling CONFIG_DEBUG_FS in defconfig to disable Debug-FS,
debugfs functions like debugfs_create_dir will fail.

Use function debugfs_initialized() to check if debugfs
functionality is enabled before calling any debugfs functions.

This allows us to by-pass debugfs initialization if debugfs
is not enabled.
