msm: vidc: fix tier and level issue for hevc

Browse source 
- Bits: 0-27 are used to specify the level
  information and bits 28-31 are reserved for
  non-level information. For HEVC, these 4 bits(MSB)
  are used for communicating the tier info.
- CTS tc will set the tier first, the level
  next and the same is set to firmware. In
  doing so, the level will override the tier value
  which is set earlier and the same is communicated to
  the firmware resulting in level info mismatch.
- Fix here is to extract the 4 MSB bits containing the
  tier info and add it to the level value, then communicate
  it to the firmware.
