Declared 32 bit unsigned int as static constant inside a function and
replaced u32[] {x,y} as canvas3, canvas4 in codec_h264.c
This indicates the value of canvas indexes will remain constant
throughout execution.

Changes from v3:- Made commit message under 75 characters per line.
Changes from v2:- Rebased this patch and made changes against mainline code
Changes from v1:- Rectified mistake by declaring u32 as static const
properly as static const u32 canvas'x'[]
