Allocates a uciOnPuschCsi2Ctrl object and returns a handle in the address provided by the caller.
Returns CUPHY_STATUS_INVALID_ARGUMENT if pUciOnPuschCsi2CtrlHndl is NULL.
Returns CUPHY_STATUS_ALLOC_FAILED if a uciOnPuschCsi2Ctrl object cannot be allocated
Returns CUPHY_STATUS_SUCCESS if allocation and initialization were successful
