From: Andi Shyti <andi.shyti@xxxxxxxxxxxxxxx> [ Upstream commit 592b228f12e15867a63e3a6eeeb54c5c12662a62 ] 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.
