Currently ACR header files are part of "include/nvgpu/acr/" folder &
ACR interfaces are not used by any other UNIT which allows headers to
keep restricted to ACR unit, as ACR can be divided into two stage
process like blob preparation & bootstrap, so moved header files from
of "include/nvgpu/acr/" to "nvgpu/common/acr/" to respective blob/
bootstrap/acr header files along with its dependent interfaces, this
allows interfaces restricted to header file based on operation it does.
With this any access to ACR must go through provided public functions,
this header move change caused large code modification & required to
