Revert "drm/i915/dp: Use auxch precharge value of 5 everywhere"
This reverts commit 092945e11c5b84f66dd08f0b87fb729715d377bc.
This commit prevents a DP screen from properly training the link.
Oddly enough it works, once the machine has been warm-booted with an
older kernel.
According to DP docs this _should_ have been the right precharge time.
Also, the commit that originally introduces this was just general snb
DP enabling and didn't mention any specific reason for this special
value. Whatever, trust the reporter that this makes things worse and
let's just revert it.
v2: Less spelling fail.
