[Intel gfx][assembler][i-g-t PATCH] assembler/bdw: Update write(...)

["Xiang, Haihao" <haihao.xiang@xxxxxxxxx>]

From: "Xiang, Haihao" <haihao.xiang@xxxxxxxxx>

write(...) is used for Render Target Write and Media Block Write.
The two message types no longer share the same cache agent on GEN8,
So a parameter is needed for cache agent. The 4th parameter of write()
is used for write commit bit which has been removed since GEN7. Hence
we can re-use the 4th parameter as cache agent on GEN8
