From: Nas Chung <[e-mail]>

Add the vpuapi layer of the wave5 codec driver.
This layer is used to configure the hardware according
to the parameters.

I haven't found any to this functions outside this, you can make it static and
remove it prototype from wave.h

You may want to replace this by:
wave5_send_query(..., GET_VPU_INFO);

Could
memset(&p_enc_info->vb_work, 0, sizeof(p_enc_info->vb_work));
be useful here ?
