[Intel-gfx] [PATCH 12/18] drm/i915/dsi: Group DPOunit clock gate workaround with PLL enable

[Hans de Goede]

Move the DPOunit clock gate workaround to directly after the PLL enable.

The exact location of the workaround does not matter and there are 2
reasons to group it with the PLL enable:

1) This moves it out of the middle of the init sequence from the spec,
   making it easier to follow the init sequence / compare it to the spec

2) It is grouped with the pll disable call in intel_dsi_post_disable,
   so for consistency it should be grouped with the pll enable in
   intel_dsi_pre_enable
