U-Boot either supports USB host or device mode for a node at a time in the
device tree nodes. To support both host and dfu bootmodes, dr_mode is set
to "peripheral" by default and then fixed based on the mode selected by
the boot mode config dip switches on the board.
This needs to happen before the cdns3 generic layer binds the usb device
to a host or a device driver. Therefore, use fdtdec_setup_board()
implementation to fixup the device tree property.

Add support command for debugging K3 power domains. This is useful with
the HSM rearch setup, where power domains are directly controlled by SPL
instead of going through the TI SCI layer. The debugging support is only
available in the u-boot codebase though, so the raw register access
power domain layer must be enabled on u-boot side for this to work. By
default, u-boot side uses the TI SCI layer, and R5 SPL only uses the
direct access methods.

Clock rates are cached within the individual clock nodes, and right now

If a clock provider is not ready for assigning default rates/parents
during its probe, it may return -EPROBE_DEFER directly from xlate.
Handle this special case properly by skipping the entry and adjusting the

phase then.

Some clocks are not associated to a DM node, so just parsing the DM is not
