MLK-20440 dts: ecspi: Add ecspi and its slave dts files for imx6ul
For ECSPI test, add these two dts files.
imx6ul-14x14-evk-ecspi.dts: enable ecspi4 function. Because ethernet2
uses the same pins with ecspi4, so disable fec1/fec2.
imx6ul-14x14-evk-ecspi-slave.dts: Add "spi-slave" attribute to enable
slave mode.
Wire Connection:
J1704:
3 - SCS
4 - MOSI
5 - MISO
6 - SCK
7 - GND
Modify "Makefile" to build these two dts files.
