vgsp: m78 - lane-enable skip mask + best-effort lane tail (#1063 no longer aborts it)
gsp_phys_rmcall_gr_lane_skip: bit0 skips #1059 CILP mode, bit1 skips #1061
timeslice, bit2 skips #1063 device-sched. Used to bisect which lane-enable
control arms the forwarded QMD enqueue and which one leaves the scheduling
state that ends in the dispatch-time context save. Also makes the m76 lane
tail independent of #1063 (always refused 0x1f by the server).
