In preparation of the next patch align with the datasheet (BSPEC 47112) with the naming of the pipe control set of flag values. The variable "flags" in gen12_emit_flush_rcs() is applied as a set of flags called Bit Group 1.
Define also the Bit Group 0 as bit_group_0 where currently only PIPE_CONTROL0_HDC_PIPELINE_FLUSH bit is set.
