ARM: dts: imx: add i.mx6ulz and i.mx6ulz 14x14 evk support

i.MX6ULZ is new SoC of i.MX6 family, compared to i.MX6ULL,
it removes below modules:

- UART5/UART6/UART7/UART8;
- PWM5/PWM6/PWM7/PWM8;
- eCSPI3/eCSPI4;
- CAN1/CAN2;
- FEC1/FEC2;
- I2C3/I2C4;
- EPIT2;
- LCDIF;
- GPT2;
- ADC1;
- TSC;

This patch adds support for i.MX6ULZ and i.MX6ULZ 14x14 EVK
board.
