qualcomm/ipq40xx: add vector operation method to SPI

Adding spi_xfer_two_vectors as .xfer_vector for ipq40xx spi_ctrlr.
    Commit c2973d196d1 ("UPSTREAM: spi: Get rid of SPI_ATOMIC_SEQUENCING")
    has added a new driver method xfer_vector to support combined write-read
    operation within a single CS cycle. The method is wrapped in the
    spi_xfer_vector() API. When spi_ctrlr structure does not have
    xfer_vector method, API calls write and read operations sequentially.
    However the QCA40xx SPI driver has "forced" CS activation-inactivation
    in xfer method, so individual operation will break CS after write
    operation, making combined write-read cycle broken.
    Adding xfer_vector method to spi_ctrlr is a simple fix to prevent this.
