Subject: [PATCH v2] ARM: dts: imx25: fix usbhost1 node

The usb port represented by &usbhost1 uses an USB phy internal to the
SoC. We add the phy_type to the base dtsi so the board dts only have to
overwrite it if they use a different configuration. While at it we also
pin the usbhost port to host mode and limit the speed of the phy to
full-speed only, which it is only capable of.

Signed-off-by: Michael Grzeschik <m.grzeschik@...gutronix.de>

v1 -> v2: added the maximum speed limitation of the internal phy
