spi: imx: introduce fifo_size and has_dmamode in spi_imx_devtype_data
Different ECSPI controller has different fifosize and DMA capability,
instead of calling functions to identify these information by check
devtype. add fifo_size and has_dmamode to spi_imx_devtype_data.
so that these information can be directly accessed.
