witherspoon-128: Remove mbox node from device tree

The mbox device driver was never upstreamed and has been dropped
from the linux tree. Remove the node from the witherspoon-128 system
as it has already been removed from the upstreamed systems.
Also rebase the patch on top of the latest linux dev-5.2 branch.
