[Mesa-dev] [PATCH v4 03/18] intel/genxml: Use a single field for clear color address on gen10.

[Rafael Antognolli]

genxml does not support having two address fields with different names
but same position in the state struct. Both "Clear Color Address"
and "Clear Depth Address Low" mean the same thing, only for different
surface types.

To workaround this genxml limitation, rename "Clear Color Address"
to "Clear Value Address" and use it for both color and depth. Do the
same for the high bits.

TODO: add support for multiple addresses at the same position in the
xml.

v2: Combine high and low order bits into a single address field.
