2018-03-09soc/intel/skylake: Move PCR DMI programming into bootblockSubrata Banik
As per PCH BWG 2.5.16, set up LPC IO Enables PCR[DMI] + 2774h bit [15:0] to the same value program in LPC PCI offset 82h. Also this cycle decoding is only allowed to set when SRLOCK is not set. Hence move the required programming from lpc.c to pch.c. Also only enable COM port ranges if CONFIG_DRIVERS_UART_8250IO Kconfig is selected.

2017-12-13soc/intel/skylake: Enable LPC IO Decoding on PCRpraveen hodagatta pranesh
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.
