modules/pcie/*: fix DDR depth generic by importing from ipcores_pkg

The previous DDR depth was hardcoded as 30, which is right for kc705 board, but not for AFC. This fixes that by using the ipcores_pkg definitions which are respective to the DDR definitions of the used board. This should help github issue #45, but in my tests it didn't solve it just yet. Nonethless, this was wrong anyway.
