arm: dts: 8226: Disable otg-disable-reset flag

When switching from peripheral to host mode, usb controller reset is
not happening as otg-disable-rese flag is enabled. For the USB host
mode functionality to work it is required that usb controller reset
should happen when switching from peripheral to host mode as per
suggested by hardware designers.

Hence fixing the issue by disabling the otg-disable-reset flag which
would result in usb controller reset as part of switching from
peripheral to host mode.
