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. https://review.coreboot.org/#/c/14040/ This doesn't handle the case where the FSP has PcdLpssSioEnablePciMode set to disable and the devicetree set to default.
