[PATCH v2 00/13] Add support for USB host and peripheral bootmodes on am65x-idk

The following patches add support for USB mass storage and USB dfu
bootmodes on am654x-idk.

Because of space constrains and the size of the USB stack,
there are two different usbmsc and usbdfu defconfigs for building R5 SPL.
Fitting both of these into one defconfig requires some changes in the
USB subsystem which is a longer term effort

Using fdtdec_board_setup() function override in patch 6 instead of open coding
