board/freescale/common/cds_pci_ft.c: Fix rotate wrong cells in interrupt-map property

For linux 3.x, the size of each item in interrupt-map property is 9 not 7.
Don't use the static value and calculate the size with following cells:
	PCI #address-cells, PCI #interrupt-cells,
	PIC address, PIC #address-cells, PIC #interrupt-cells.
