No need to use an intermediate 'dma-offset' property in the
chipset object. Alias the property, so when the machine (here
r2d-plus) sets the value on the chipset, it is propagated to
the OHCI object.

Note we can rename the chipset 'base' property as 'dma-offset'
since the object is a non-user-creatable sysbus type.
