drm/i915: Unduplicate CHV encoders' post pll disable code
The exact same code was used by HDMI and DP encoders, so move it to
intel_dpio_phy.c.
v2: Fix typo in the commit message. (Jim Bride)
v3: Call the new function chv_phy_post_pll_disable() instead of
chv_phy_post_disable(), as it should be called after the pll
is disabled. (Ville)
