addy ke 64e36824b3 spi/rockchip: add driver for Rockchip RK3xxx SoCs integrated SPI
In order to facilitate understanding, rockchip SPI controller IP design
looks similar in its registers to designware. But IC implementation
is different from designware, So we need a dedicated driver for Rockchip
RK3XXX SoCs integrated SPI. The main differences:

- dma request line: rockchip SPI controller have two DMA request line
  for tx and rx.

- Register offset:
                  RK3288        dw
  SPI_CTRLR0      0x0000        0x0000
  SPI_CTRLR1      0x0004        0x0004
  SPI_SSIENR      0x0008        0x0008
  SPI_MWCR        NONE          0x000c

  SPI_VERSION     NONE          0x005c
  SPI_DR          NONE          0x0060

- register configuration:
  such as SPI_CTRLRO in rockchip SPI controller:
    cr0 = (CR0_BHT_8BIT << CR0_BHT_OFFSET)
        | (CR0_SSD_ONE << CR0_SSD_OFFSET);
    cr0 |= (rs->n_bytes << CR0_DFS_OFFSET);
    cr0 |= ((rs->mode & 0x3) << CR0_SCPH_OFFSET);
    cr0 |= (rs->tmode << CR0_XFM_OFFSET);
    cr0 |= (rs->type << CR0_FRF_OFFSET);
  For more information, see RK3288 chip manual.

- Wait for idle: Must ensure that the FIFO data has been sent out
  before the next transfer.
