This patch adds a debugfs node to show DCE boot status. It also adds following dce boot marker in logs - DCE_BOOT_DONE - DCE_BOOT_FAILED JIRA TDS-5691 Change-Id: Iada5c1234e5e5f1a5e7afd88dcb94c2da6a3fe1c Signed-off-by: Mahesh Kumar <mahkumar@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-t23x/+/2361287 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Santosh Galma <galmar@nvidia.com> Reviewed-by: Arun Swain <arswain@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: Santosh Galma <galmar@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
