intel/fsp_baytrail: Enable LPSS in ACPI mode
This change fixes LPSS ACPI mode. Previously, enabling ACPI mode would
result in unusable devices, as the resources were set to 0 and the devices
were disabled.
lpss.c was copied from intel/baytrail with a few minor adjustment for the
different config structure.
ACPI mode requires setting PcdLpssSioEnablePciMode==LPSS_PCI_MODE_DISABLE
and applying the patch that disables clearing gnvs.

This doesn't handle the case where the FSP has PcdLpssSioEnablePciMode
set to disable and the devicetree set to default.
