msm-vidc: calculate encode output buffer size considering 10-bit 

In case of opaque color format the bit depth will be known with
first ETB. Existing logic calculates output buffer size based on 
8-bit which won't be sufficient for 10-bit.
So consider 10-bit by default while calculating encoder output
buffer size.
