Subject: drm/nouveau/gr/gp10b: Use gp100_grctx and gp100_gr_zbc
Git-commit: 90e2e96ea37745ae18a1ff7b322e3321731828e4
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
gp10b doesn't have all the registers that gp102_gr_zbc wants to access,
which causes IBUS MMIO faults to occur. Avoid this by using the gp100
variants of grctx and gr_zbc.
