What should be done in addition to Richard's patch in order to get USB
host to work on mx28evk?

Ah right, you need to toggle the power supply (vbus) GPIO.

Toggle it where?

I see the following:

reg_usb0_vbus: usb0_vbus {
compatible = "regulator-fixed";
regulator-name = "usb0_vbus";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&gpio3 9 0>;
enable-active-high;

So the gpio3_9 will turn on the vbus.

What is missing?
