[Intel-gfx] [PATCH v6 2/4] drm/i915: Add _TRANS2()

[José Roberto de Souza]

A new macro that is going to be added in a further patch will need to
adjust the offset returned by _MMIO_TRANS2(), so here adding
_TRANS2() and moving most of the implementation of _MMIO_TRANS2() to
it and while at it taking the opportunity to rename pipe to trans.
