haptics: awinic: add haptic context while flat-up
-1, add haptic context whild flat-up reduce the gain of vibration -2, disable this feature when the bootmode is factory Change-Id: I75a871cf94af54f375a42be54ddcd1d380972797 Signed-off-by: yangjq <yangjq@lenovo.com> Reviewed-on: https://gerrit.mot.com/1374681 SLTApproved: Slta Waiver SME-Granted: SME Approvals Granted Tested-by: Jira Key Reviewed-by: Jianqi Yang <yangj@motorola.com> Submit-Approved: Jira Key
