Christian König 1bcb04f758 drm/radeon: fix and simplify pot argument checks v3
GART and VRAM size limits need to be a power of two.
Fix values greater than 1GB and simplify those checks a bit.

v2: also fix radeon_vram_limit usage, and simplify test even more.
v3: agd5f: fix spelling as noticed by Klaus Schnass
