IB/core: Add UVERBS_METHOD_REG_MR on the MR object
This new method enables us to use a single ioctl from user space which supports the below variants of reg_mr [1]. The method will be extended in the next patches from the series with an extra attribute to let us pass DMA handle to be used as part of the registration. [1] ibv_reg_mr(), ibv_reg_mr_iova(), ibv_reg_mr_iova2(), ibv_reg_dmabuf_mr().
