Alexander Motin 7aafa7c368 Allow splitting PLX NTB BAR2 into several memory windows.
Address Lookup Table (A-LUT) being enabled allows to specify separate
translation for each 1/128th or 1/256th of the BAR2.  Previously it was
used only to limit effective window size by blocking access through some
of A-LUT elements.  This change allows A-LUT elements to also point
different memory locations, providing to upper layers several (up to 128)
independent memory windows.  A-LUT hardware allows even more flexible
configurations than this, but NTB KPI have no way to manage that now.
