uld set.

    Also remove the code that sets this register from the old
    location: lpt_pch_enable.

  5 - Properly program FDI_RX_MISC pwrdn lane values on HSW

  6 - Wait only 35us for the FDI link training

    First we wait 30us for the FDI receiver lane calibration, then we
    wait 5us for the FDI auto training time.

  7 - Remove an useless indentation level on hsw_fdi_link_train

    We already "break" when the link training succeeds.

  8 - Disable FDI_RX_ENABLE, not FDI_RX_PLL_ENABLE

    When we fail the training.

  9 - Change Haswell FDI link training error messages

    We shouldn't call DRM_ERROR when still looping through voltage
    levels since this is expected and not really a failure. So in this
    commit we adjust the error path to only DRM_ERROR when we really
    fail after trying everything.

    While at it, replace DRM_DEBUG_DRIVER with DRM_DEBUG_KMS since
    it's what we use everywhere.

  10 - Try each voltage twice at hsw_fdi_link_train

    Now with Daniel Vetter's suggestion to use "/2" instead of ">>1".

- mention in comment that we test each voltage/emphasis level twice
- realing arguments of the only untouched reg write, it spilled over
  the 80 char limit ...]
