sandybridge/gma_lvds: support both Sandy&Ivy on one board
Sandy and Ivy Bridge processors use the same socket, and a mainboard with the socket can support both types of CPUs. However, they use different native graphics init code for LVDS and cause a crash if running the wrong code. This change detects the CPU type and then selects the right code to run. It will add some more code in ramstage. It also merges the {SANDY,IVY}BRIDGE_LVDS symbol to one SANDYBRIDGE_IVYBRIDGE_LVDS. Tested on a Lenovo T520 with i7-2630qm and i7-3720qm Signed-off-by: Iru Cai <mytbk920423@gmail.com> Change-Id: I4624759f9c92d56d547db1ab4b9a1d611a182a91 Reviewed-on: https://review.coreboot.org/12087 Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com> Tested-by: build bot (Jenkins)
