Subject: [PATCH v2 2/2] resource: Convert DEFINE_RES_NAMED() to be compound literal

Currently DEFINE_RES_NAMED() can only be used to fill the static data.
In some cases it would be convenient to use it as right value in the
assignment operation. But it can't be done as is, because compiler has
no clue about the data layout. Converting it to be a compound literal
allows the above mentioned usage.
