Subject: [PATCH v3 1/2] ARM: dts: imx25: consolidate properties of usbhost1 in dtsi file

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.

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

v2 -> v3: - moved phy speed limitation to extra patch
- reworded subject line
