mb/intel/tglrvp: Add initial mainboard code

This is a initial mainboard code aimed to serve as base for
further mainboard check-ins.

This is a copy patch from icelake_rvp as on commit ID:
I64db2460115f5fb35ca197b83440f8ee47470761

Below are the changes done over the copy patch:

 1. Rename "Icelake" with "Tigerlake".
 2. Replace "icelake_rvp" with "tglrvp".
 3. Rename "icl" with "tgl".
 4. Remove unwanted SPD file, add empty SPD as
    placeholder.
 5. Replace "soc/intel/icelake" with "soc/intel/tigerlake".
 6. Empty romstage_fsp_params.c, to fill it later with
    SOC specific config.
 7. Empty GPIO configuration, to be filled as per board.
 8. Change copyright year to 2019.
 9. Add board support namely BOARD_INTEL_TGLRVP_UP3
 10. Replace icl_u and icl_y variant with tglrvp variant.
 11. Remove basebord gpio.c and rely on variant override.
 12. Remove HDA verb table and config support.

Changes to follow on top of this:
 1. Add correct memory parameters, add SPDs.
 2. Clean up devicetree as per tigerlake SOC.
 3. Add GPIO support.
 4. Update chromeos.fmd to make 32MB BIOS region.
 5. clean up and make empty devicetree setting

TEST=Build tigerlake rvp board
