media: rkvdec: Add required padding
The addresses of two elements of the segmap[][] member are passed to the
hardware which expects 128-bit aligned addresses. However, without this
patch offsetof(struct rkvdec_vp9_priv_tbl, segmap[0]) is an odd number
(2421) but the hardware just ignores the 5 least significant bits of the
address. As a result, the hardware writes the segmentation map to incorrect
locations.
Inserting 11 bytes of padding corrects this situation by making the said
addresses divisible by 16 (i.e. aligned on a 128-bit boundary).
