praveen hodagatta pranesh d6dffdc1fa soc/intel/skylake: Enable LPC IO Decoding on PCR 
According to the PCH BIOS Spec (Doc#549921/Rev-2.3.4),
section 2.5.1.6, it is a requirement to program the same
value programmed in LPC "PCI offset 82h" into "PCR[DMI]+2774h"
to fully enable the Lpc IO enable decoding which is missing in
current source.

Without above changes, Skylake Saddlebrook platform with a
SIO does not boot.
