ENGR00306875-1 Revert "ENGR00305624-2 ASoC: imx-hdmi-dma: Correct the appl pointer"

After change the pointer, ALSA lib would re-copy the initial data to
DMA buffer because the pointer is pointing the zero position at the
beginning, which results an audiable duplicated playback at the first
eight periods.

Even though dropping this patch would cause pointer being incorrectly
estimated. But to maintain the sanity of basic playback, we revert
the previous patch.

This reverts commit 5d0d4e1558fa0c235691436e1c5d26d9c8950775.
