To keep things as organized as possible, copy the bootph-all properties
from U-Boot for the packet DMA controller to indicate it should be
available during all phases of bootup.

Above isn't a valid reason to add bootph-all properties to a node. You
would need to say why this DMA controller is needed during all phases of
boot, does this enable a certain boot-mode? Fix $subject to reflect the
same.
