drm/i915: Relocate intel_ddi_get_buf_trans_*() functions

Browse Source 
We'll want to use the intel_ddi_get_buf_trans_*() functions a bit
earlier in the file, so move them up. While at it start using them
in the iboost setup to get rid of the platform checks there.

v2: Rebase due to BDW FDI buf trans fix
