Revert "msm_fb: display: add pipe commit ioctl"

This reverts commit dba1bab9026749a7213a02658a09901da844ee1e.
msm_fb: display: Add MSMFB_OVERLAY_COMMIT ioctl.

MSMFB_OVERLAY_COMMIT ioctl is used to display on external.
This is used instead of the default PAN mechanism to avoid delays in that path.
This ioctl for external also waits for DMAE thus fixing tearing.
