regmap: debugfs: fix possbile NULL pointer dereference
commit 2c98e0c1cc6b8e86f1978286c3d4e0769ee9d733 upstream.
If 'map->dev' is NULL and there will lead dev_name() to be NULL pointer
dereference. So before dev_name(), we need to have check of the map->dev
pionter.
We also should make sure that the 'name' pointer shouldn't be NULL for
debugfs_create_dir(). So here using one default "dummy" debugfs name when
the 'name' pointer and 'map->dev' are both NULL.
