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
}
}
Is this just a cosmetic change or is this trying to workaround
some edma related init order issue?
Please ignore this patch. Was trying to workaround some dma and phy related issues.
The same got fixed with following
