configs: am62x_evm_*: Fix USB DFU configuration
CONFIG_USB_XHCI_DWC3 is not required for AM62x as the XHCI
driver is registered through the dwc3-generic driver.
CONFIG_USB_XHCI_DWC3 causes problems by hijacking the
USB controller even if it is not set for Host mode in
device tree.
'dm tree' output after 'usb start' is fixed from

[notice that 'xhci-dwc3' and 'usb_hub' drivers are probed
for both USB instances although the first instance
is supposed to be 'peripheral' only]
