drm/radeon/kms: remove benchmarks shorter than one page
copy_blit operation works only on integral number of pages
so benchmarks shorter than one page size (4K) do not make sense
v2: use RADEON_GPU_PAGE_SIZE instead of "magic" 1024 number and
sweep sizes between 1 * <page_size> to 16K * <page_size> doubling
the size in each iteration; we get the same coverage, as
in the original benchmark, but guarantee integer multiples
of page size
v3: add whitespace between '*' operator per review received from
