This reverts commit 32dfdfbb01.
The update caused an issue on T480:
Backlight comes on, then off, then on, then off, repeatedly, and
never gets to the payload. Will have to investigate further.

Subject: [PATCH 22/41] mb/dell: Add S3 SMI handler for Dell Latitudes
|
|
|
|
Integrate the previously added mec5035_smi_sleep() function into
|
|
mainboard code to fix S3 suspend on the SNB/IVB Latitudes and the E7240.
|
|
The E6400 does not require the EC command to sucessfully suspend and
|
|
resume from S3, though sending it does enable the breathing effect on
|
|
the power LED while in S3. Without it, all LEDs turn off during S3.
