Disable two pass partition search on lowres and midres

Currently two pass partition search has an average slow down of 2.3% on
lowres and 4% on midres when the PSNR are limited to 35dB to 45B. There
is however a 9% average speed up on hdres. This patch enables it only on
hdres speed 1 and speed 2.
