imx: mx6ull-14x14-evk: enable DM QSPI driver

Browse Source 
To support QSPI DM driver
 - Add spi0 alias for qspi node. Which is used for bus number 0.
 - Modify the n25q256a@0 compatible property to "spi-flash".
 - Modify spi4 (gpio_spi) node to spi5
 - Define DM SPI/QSPI related config to enable QSPI
