soc/intel/skylake: Add support for CmdTriStateDis UPD in devicetree
This patch adds the support for CmdTriStateDis FSP upd in skylake
soc structure so that we can define it in devicetree.CmdTriStateDis
needed to be set for the skylake/kabylake based boards where LPDDR3
design is without RTT for CMD/CTRL.We need to set this bit for those
designs for the margin to be proper.
BUG=b:111812662
TEST=Run memtester app and also webgl fishtank on
the LPDDR3 kabylake boards and also check the
margin data is proper in FSP.
