[Intel-gfx] [PATCH v3 3/6] drm/i915: Change the placement of some static functions in intel_dp.c

[Manasi Navare]

These static helper functions are required to be used within upfront
link training related functions so they need to be placed at the top
of the file. It also changes macro dev to dev_priv.

v3:
* Add cleanup to other patch (Mika Kahola)
v2:
* Dont move around functions declared in intel_drv.h (Rodrigo Vivi)
