linux-ti-staging: Add new device tree target am572x-idk-pru-excl-uio.dtb
This new device tree file is to support pruss with uio based drivers alone. Adds uio entries for pruss susbsystem and disables other drivers controlling the same. New dtb is added only if ENABLE_TI_UIO_DEVICES is enabled. Signed-off-by: Sam Nelson <sam.nelson@ti.com> Signed-off-by: Denys Dmytriyenko <denys@ti.com>
