[ Upstream commit 1444232152ea33f5ae41fc14bade3e74d642b634 ]
In existing video driver implementation vpp frequency calculation in calculate_inst_freq() is always zero because the value of vpp_freq_per_mb is always zero for decoder.
Fixed this by correcting the calculating the vpp frequency calculation for decoder.
