[PATCH v1] verdin-am62: add DFU, USB and UUU fastboot support

[Vitor Soares <ivitro@gmail.com>]

From: Vitor Soares <vitor.soares@toradex.com>

Enable USB host as well as USB gadget and DFU support for a53 and r5
configs. Also, enable UUU fastboot support to download files with
the UUU tool from a53.

Additionally, configure usb0 to peripheral mode and add extra
environment for DFU use.
