mb/gigabyte/ga-b75m-d3{h,v}: Various cleanups
- Enable LPC TPM support in Kconfig and add pc80/tpm to devicetree
- Enable VBT support in Kconfig and add VBT files extracted from
vendor firmware
- Remove IGPU VBIOS entries from Kconfig
- Remove unused PS2 definitions in superio.asl
- Add PWRB ACPI device entry to mainboard.asl
- Remove duplicate chipset register initialization from mainboard.c
- Move ITE Super I/O configuration to mainboard_config_superio in
romstage.c
