drm/amdgpu: restrict bo mapping within gpu address limits

mainline inclusion
from mainline-v5.9-rc1
commit 8b80d74b
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9J3KG
CVE: CVE-2024-26922

Reference: https://lore.kernel.org/all/20200602182735.5940-1-rajneesh.bhardwaj@amd.com/



--------------------------------

Have strict check on bo mapping since on some systems, such as A+A or
hybrid, the cpu might support 5 level paging or can address memory above
48 bits but gpu might be limited by hardware to just use 48 bits. In
general, this applies to all asics where this limitation can be checked
against their max_pfn range. This restricts the range to map bo within
pratical limits of cpu and gpu for shared virtual memory access.
