drm/amdgpu: kernel page size fixes from AMD's drm-next branch

Cherry-pick 3 fixes from AMD's drm-next branch that fix issues in amdgpu on systems where kernel page size is not 4KB like ppc64le. Tested on Radeon PRO WX4100, but could fix other cards too.

added Acks::videoOK label and removed Acks::videoNeedsReview label

all 3 commits are now in https://gitlab.freedesktop.org/agd5f/linux/-/commits/drm-fixes-5.12, so perhaps they will be merged to mainline 5.12 soon and we won't need this MR

added Include in Releases label

I have just tagged it with "include in releases". This will bring it into dist-git builds without having to merge the MR, and it can just stay this way until it is properly merged upstream. The 5.11 version of this one for stable Fedora is already merged and should be included in the 5.11.12 builds.

Ack, the fixes are now in https://cgit.freedesktop.org/drm/drm/log/?h=drm-fixes, which is one merge till mainline, I believe.

removed Include in Releases label

Looks like this is upstream now, closing this one out.
