[ Upstream commit d5349775c1726ce997b8eb4982cd85a01f1c8b42 ]
[why]
nv14 previously inherited soc bb from generic dcn 2, did not match
watermark values according to memory team
[how]
add nv14 specific soc bb: copy nv2 generic that it was
using from before, but changed num channels to 8

[ Upstream commit 07dc3678bacc2a75b1900febea7d996a31f178a2 ]
Store the IOMMU mapping created by the device core of each Exynos DRM
sub-device and restore it when the Exynos DRM driver is unbound. This
fixes IOMMU initialization failure for the second time when a deferred
probe is triggered from the bind() callback of master's compound DRM
driver. This also fixes the following issue found using kmemleak
detector:
