drivers/intel/gma: fix opregion SCI register for Atom platforms
Most Intel platforms use separate registers for software-based SMI (0xe0) and SCI (0xe8), but Atom-based platforms use a single combined register (0xe0) for both. Adjust opregion implementation to use the correct register for Atom-based platforms. Test: Boot Windows on Atom-based ChromeOS device with Tianocore payload and non-VBIOS graphics init; observe Intel display driver loaded correctly and internal display not blank. (requires additional change for Atom platforms to select CONFIG_INTEL_GMA_SWSMISCI) Change-Id: I636986226ff951dae637dca5bc3ad0e023d94243 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/23696 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>
