From: Konstantin Porotchkin <kostap@xxxxxxxxxxx> Update the settings for AP806 SDHCI interface according to latest Xenon drivers changes. - no need to select the PHY slow mode anymore - recommended to add HS400 support at 1.8V signalling on AP806-B0 - fix the bus witdth for A8040 DB from 4 to 8 bits.
