[PATCH v3 03/13] software node: get rid of property_set_pointer()

[Dmitry Torokhov]

Instead of explicitly setting values of integer types when copying property
entries lets just copy entire value union when processing non-array values.

When handling array values assign the pointer there using the newly introduced
"raw" pointer union member. This allows us to remove property_set_pointer().
