spapr_iommu: Get rid of window_size in sPAPRTCETable

Browse source 
This removes window_size as it is basically a copy of nb_table
shifted by SPAPR_TCE_PAGE_SHIFT. As new dynamic DMA windows are
going to support windows as big as the entire RAM and this number
will be bigger that 32 capacity, we will have to do something
about @window_size anyway and removal seems to be the right way to go.

This removes dma_window_start/dma_window_size from sPAPRPHBState as
they are no longer used.
