spapr/ddw: Reset DMA when the last non-default window is removed
PAPR+/LoPAPR says:
===
The platform must restore the default DMA window for the PE on a call
to the ibm,remove-pe-dma-window RTAS call when all of the following
are true:
a. The call removes the last DMA window remaining for the PE.
b. The DMA window being removed is not the default window
===
This resets DMA as PAPR mandates.
