msm: camera: common: Add private data in mini dump

Browse Source 
Each driver can pass private data in mini dump callback register, so
when mini dump is invoked, the mini dump handler will pass the private
data to the callback associated with the driver. With the private data,
ICP driver can determine which mini dump callback corresponds to which
ICP device/hw mgr.
