arm: dts: zynq-zed-adv7511-adaq4003: Switch to spi-engine-ex

The new AD4000 series driver uses SPI prepare message mechanism which is
only supported by the new spi-engine-ex driver (spi-axi-spi-engine-ex.c) in
ADI Linux tree.
Update AD4000 series device trees to match the upstream-like SPI-Engine
driver.
