drm/i915: fix to setup display reference clock control on Ironlake
For new stepping of PCH, the display reference clock
is fully under driver's control. This one trys to setup
all needed reference clock for different outputs. Older
stepping of PCH chipset should be ignoring this.
This fixes output failure issue on newer PCH which requires
driver to take control of reference clock enabling.
