[PATCH v4 02/14] software node: introduce PROPERTY_ENTRY_ARRAY_XXX_LEN()

[Dmitry Torokhov]

Sometimes we want to initialize property entry array from a regular
pointer, when we can't determine length automatically via ARRAY_SIZE.
Let's introduce PROPERTY_ENTRY_ARRAY_XXX_LEN macros that take explicit
"len" argument.
