[Intel-gfx] [RFC] drm/i915: Extend PARAMS_FOR_EACH macro with more data

Currently our PARAMS_FOR_EACH macro contains only param type and name.
We use this macro to define struct members, but later on we initialize
this struct using handcrafted code, which leads in some cases to use
mismatched value vs. type. Let's extend our root macro with param
default value to keep them in sync. Also drop ; from the macro to allow
more flexible usages.
Later on we can also add there permission, unsafe tag and description.
