purism/librem_skl: Enable VMX and Intel SpeedStep in devicetree
Although VmxEnable is currently ignored by FSP, a forthcoming patch
explicitly enables it in coreboot, so set it in anticipation of that.
Enable Intel SpeedStep to ensure the ACPI tables are generated for
the C-states/P-states which are required for the xen-acpi-processor
module to be loaded. Without it, the Qubes 4.0-rc4 installer will
complain at boot about modules that could not be loaded.
