Re arrange the USB dt for AM33xx to take it a bit closer
to the hardware configuration.

The USBSS is designed as follows

USB control Module	0x44e10_0620

USBSS			0x4740_0000

USB0			0x4740_1000
USB0_PHY		0x4740_1300
USB0_CORE		0x4740_1400

USB1			0x4740_1800
USB1_PHY		0x4740_1b00
USB1_CORE		0x4740_1c00

CPPI DMA Controller	0x4740_2000
CPPI DMA Scheduler	0x4740_3000
Queue Manager		0x4740_4000

So model the DT as follows
USBSS {
    usb_ctrl_mod: {
        0x44e10_0620
    }
    usb0: {
    0x4740_1000
    0x4740_1400
    }
    usb0_phy:{
    0x4740_1300
    }
    usb1:{
    0x4740_1800
    0x4740_1c00
    }
    usb1_phy: {
    0x4740_1b00
    }
    cppi41dma: {
    0x4740_2000
    0x4740_3000
    0x4740_4000
    }
}
