[Intel-gfx] [PATCH v2 1/2] drm/i915: Fix DP_AUX_CH_CTL_TIME_OUT naming

[James Ausmus]

Rename DP_AUX_CH_CTL_TIME_OUT_1600us to DP_AUX_CH_CTL_TIME_OUT_MAX, as
the meaning of the (3 << 26) value varies per platform, but it's always the
maximum timeout for that platform. Pre-CNL it means 1600us, and for CNL
it means 3200us.

v2:
-Split in to two patches (Rodrigo)
