//| Name   : HalCm_VeboxInitSTMMHistory()
//| Purpose: Resets the portion of the Vebox STMM surface associated with
//|              motion history for temporal filtering.
//|
//| Description:
//|   This function is used by VEBox for initializing
//|   the STMM surface.  The STMM / Denoise history is a custom surface used
//|   for both input and output. Each cache line contains data for 4 4x4s.
//|   The STMM for each 4x4 is 8 bytes, while the denoise history is 1 byte
//|   and the chroma denoise history is 1 byte for each U and V.
//|   Byte    Data
//|   0       STMM for 2 luma values at luma Y=0, X=0 to 1
//|   1       STMM for 2 luma values at luma Y=0, X=2 to 3
//|   2       Luma Denoise History for 4x4 at 0,0
//|   3       Not Used
//|   4-5     STMM for luma from X=4 to 7
//|   6       Luma Denoise History for 4x4 at 0,4
//|   7       Not Used
//|   8-15    Repeat for 4x4s at 0,8 and 0,12
//|   16      STMM for 2 luma values at luma Y=1,X=0 to 1
//|   17      STMM for 2 luma values at luma Y=1, X=2 to 3
//|   18      U Chroma Denoise History
//|   19      Not Used
//|   20-31   Repeat for 3 4x4s at 1,4, 1,8 and 1,12
//|   32      STMM for 2 luma values at luma Y=2,X=0 to 1
//|   33      STMM for 2 luma values at luma Y=2, X=2 to 3
//|   34      V Chroma Denoise History
//|   35      Not Used
//|   36-47   Repeat for 3 4x4s at 2,4, 2,8 and 2,12
//|   48      STMM for 2 luma values at luma Y=3,X=0 to 1
//|   49      STMM for 2 luma values at luma Y=3, X=2 to 3
//|   50-51   Not Used
//|   36-47   Repeat for 3 4x4s at 3,4, 3,8 and 3,12
//|
//| Returns: MOS_STATUS_SUCCESS if success. Error code otherwise;
//!
