mb/system76/*: Disable IME by CMOS option
Add CMOS option to set IME mode. Default to "Disable" for CNL and TGL-H, and "Enable" for TGL-U. Not set for KBL, which uses ME_CLEANER. HECI device must be enabled in devicetree for switching modes to function correctly. Change-Id: I9b400c05c38bf76c02c4a2b113bf843b0240a75f Signed-off-by: Tim Crawford <tcrawford@system76.com>
