turnip: remove extra gmem alignment

Browse Source 
Now that we clear the PITCHALIGN" field when filling GMEM input attachment
descriptors, we can get rid of the extra tile width alignment on a630/a640.

With the "block_align_shift" value change, this brings down the default
gmem_align from 16k to 4k on a630/a640 and down from 24k to 12k on a650,
to match the gallium driver.
