[PATCH] [media] mtk-vcodec: fix type mismatches

The newly added mtk-vcodec driver produces a number of warnings in an ARM
allmodconfig build, mainly since it assumes that dma_addr_t is 32-bit wide:

mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/mtk_vcodec_enc.c: In function 'mtk_venc_worker':
mtk-vcodec/mtk_vcodec_enc.c:1030:46: error: format '%lx' expects argument of type 'long unsigned int', but argument 7 has type 'size_t {aka unsigned int}' [-Werror=format=]
  mtk_v4l2_debug(2,
mtk-vcodec/mtk_vcodec_enc.c:1030:46: error: format '%lx' expects argument of type 'long unsigned int', but argument 10 has type 'size_t {aka unsigned int}' [-Werror=format=]
mtk-vcodec/venc_vpu_if.c: In function 'vpu_enc_ipi_handler':
mtk-vcodec/venc_vpu_if.c:40:30: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  struct venc_vpu_inst *vpu = (struct venc_vpu_inst *)msg->venc_inst;

This rearranges the format strings and type casts to what they should have been
in order to avoid the warnings.
