msm: cvp: Add Qualcomm CVP driver for Kona

Add initial CVP driver source code. CVP driver helps in
interfacing of CVP hardware to be used by clients.
The driver uses CSRs from Kona HPG and IPCAT including
IRQ and HFI handling. This is a new driver deriving
source code from video driver because the functionality
for both drivers are similar.
Creating a separate driver for CVP subsystem provides
flexibility to enrich Computer Vision (CV) features
without impacting video driver. It also provides room
to optimize CV Applications' performance and power.
The initial CVP driver did not introduce any structural
change from the video driver architecture except CSR
programming and removal of non-applicable modules.
Video driver source can be found at
kernel/msm-4.19/drivers/media/platform/msm/vidc/.
