ARM: dts: imx27: Use the correct usb clock gate

USB Host1, Host2 and OTG are gated via 'usb_ipg_gate' clock, so fix it in order
to avoid the following kernel oops:

usbcore: registered new interface driver usb-storage
10024000.usb supply vbus not found, using dummy regulator
Unhandled fault: external abort on non-linefetch (0x808) at 0xf4424184
