From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>
The platforms we currently have all have LPT LP on them. As such, we
have no way to identify the new WPT PCH that will ship with Broadwell.
NOTE: For all purposes relevant to the driver that this point, LPT and
WPT are equivalent. Therefore there should be no need to actually change
this for some time.
v2: Don't assign dev_priv->num_pch_pll any more.
v3: Rebase on top of the PCH detection changes for virtualized
enviroments.
v4 (Ben): Wrote commit message
