ARM: dts: dra7: Remove peripheral mode for usb1

U-boot automatically falls back to peripheral mode when dr_mode is set
as "otg". Therefore, there is no need to add a peripheral mode for usb1
in -u-boot.dtsi. Also am57xx board file sets up usb1 in host which
should not be overridden in -u-boot.dtsi. Therefore, remove the
peripheral mode from omap5-u-boot.dtsi.
