i965: Keep track of whether LRI is allowed in the context struct.
This stores the result of can_do_pipelined_register_writes() in the context struct so we can find out later whether LRI can be used to program the L3 configuration. v2: * Split change of gen check in can_do_pipelined_register_writes (jljusten) Reviewed-by: Jordan Justen <[email protected]> Reviewed-by: Kristian Høgsberg <[email protected]>
