amdgpu/addrlib: allow tileSplitBytes greater than row size

Carrizo row size is 1K, while tileSplitBytes is 2K for a 4xAA 32bpp
depth surface. Remove the sanity check that tileSplitBytes must be
greater than row size. There could be performance loss but may be
covered by non-split depth which enables tc-compatible read.
