Subject: drm/msm: Fix address space size after refactor.
Git-commit: f167989c673096c8d823b1292c6ee51ed266d178
Patch-mainline: v5.8-rc4
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Previously the address space went from 16M to ~0u, but with the
refactor one of the 'f's was dropped, limiting us to 256MB.
Additionally, the new interface takes a start and size, not start and
end, so we can't just copy and paste.
Fixes regressions in dEQP-VK.memory.allocation.random.*
Fixes: ccac7ce373c1 ("drm/msm: Refactor address space initialization")
