drm/i915: Fix iboost setting for DDI with 4 lanes on SKL
Bspec says: "For DDIA with x4 capability (DDI_BUF_CTL DDIA Lane Capability Control = DDIA x4), the I_boost value has to be programmed in both tx_blnclegsctl_0 and tx_blnclegsctl_4." Currently we only program tx_blnclegsctl_0. Let's do the other one as well.
