skylake boards: disable ACPI PM Timer
These devicetree patches set the ACPI PM Disabled variable to 1. This will disable the ACPI PM timer and remove from FADT table.
BRANCH=none BUG=chrome-os-partner:48646 TEST=Build for skylake board with the PmTimerDisabled policy in devicetree set to 1. iotools mmio_read32 0xfe0000fc should return 0x2. cat /sys/devices/system/clocksource/clocksource0/available_clocksource should list only "tsc hpet". acpi_pm should be removed from this list.
