msm: camera: cci: Add check for the cci master initialization

Multiple Sensor submodules can stream on same CCI master. Currently,
there is not any knowledge, whether requested master is already
initialized by other submodules. This can result in operation slave
in error, while other submodule tries to init the same master.
This change adds the boolean variable to notify cci hardware, whether
master is already initialized, and perform the operations accordingly.
