drm/exynos: ipp: introduce last_buf_id
There is no reason to tie the buf idx from userspace and the real HW DMA
channel. So to separate them, the buf idx from userspace must be stored
to return the idx when the processing is done. This patch introduces
last_buf_id to store the current processing buf id for that purpose.
