Subject: [PATCH] sky2: Increase D3 delay to sky2 stops working after suspend
Git-commit: afb133637071be6deeb8b3d0e55593ffbf63c527
Patch-mainline: v4.17-rc1
References: bsc#1051510

The sky2 ethernet stops working after system resume from suspend:
[ 582.852065] sky2 0000:04:00.0: Refused to change power state, currently in D3

The current 150ms delay is not enough, change it to 200ms can solve the
issue.
