This change is made to support 100ms VBV delay for
aggressive rate control in iris3 hw.
Video buffer verifer helps to ensure that encoded stream
doesn't overflow or underflow the decoder's buffer.
iris3 hw is capable to decode data in 100ms VBV buffer window.
Adaptive Blur (Internal encoder feature): This is other enhancement
which supports adaptive blur feature on iris3 for CBR_VFR
(Constant bit rate_Variable frame rate)/CBR_CFR
(Constant bit rate_Constant frame rate) rc types apart from
already supported VBR_CFR. Unlike iris2, there is no need to enable CAC.
Below are the listed scenarios when it is enabled/disabled on iris3-
- Supported only for 8 bits encoding (H.264 & H.265).
- By default enabled for VBR_CFR/CBR_VFR/CBR_CFR RC without CAC enabled.
- No dependency on CAC to be enabled.
- Adaptive Blur is disabled if minquality_VBR is enabled
- Adaptive Blur is supported for 3 RC types: VBR_CFR, CBR_VFR & CBR_CFR
- If any one of the features (scalar/external blur) enabled, encoder
disables adaptive-blur.
- Static property available to disable adaptive blur feature

For backward compatibilty:
- Removed CAC as parent from msm_vidc_kalama.c.
- Removed cac query from msm_vidc_adjust_blur_type in msm_vidc_control.c.
- Moved legacy code to newly created function msm_vidc_adjust_blur_type_iris2().
- Added msm_vidc_adjust_blur_type_iris2 in BLUR_TYPES in msm_vidc_waipio.c

- enable conditional compilation based on defconfig
- compile only needed files based target & vpu variant
- enabled stubs to avoid compilation issues, for all
target variant and vpu types
- add support for qcv(same lunch combo) for different
PT & VT chipsets.
