[PATCH v8 1/6] software node: rename is_array to is_inline

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

We do not need a special flag to know if we are dealing with an array,
as we can get that data from ratio between element length and the data
size, however we do need a flag to know whether the data is stored
directly inside property_entry or separately.
