Revert "venus: firmware: Correct non-pix start and end addresses" 

This reverts commit a837e5161c, which broke probing of the venus
driver, at least on the SC7180 SoC HP X2 Chromebook:

  qcom-venus aa00000.video-codec: Adding to iommu group 11
  qcom-venus aa00000.video-codec: non legacy binding
  qcom-venus aa00000.video-codec: failed to reset venus core
  qcom-venus: probe of aa00000.video-codec failed with error -110

Matthias Kaehlcke also reported that the same change caused a regression
in SC7180 and sc7280, that prevents AOSS from entering sleep mode during
system suspend.  So let's revert this commit for now to fix both issues.
