From: Colin Xu <colin...@intel.com>

In recent virtual PCH detection refactoring patch, virtual pch id
is guessed and sanity checked from dev_priv. However, on platform that
has no PCH like BXT, the guessing is wrong by mixing up PCH_NONE with
PCH_NOP.
The patch set handles such situation so that correct virtual PCH_NONE or
PCH_NOP type could be assigned accordingly. And it also add BXT to virtual
PCH detection logic.

  drm/i915: Update virtual PCH in single function
  drm/i915: Assign PCH_NONE for BXT in virtualization
