Fix IO port selection issue on MPC8544DS and MPC8572DS boards

The IO port selection is not correct on MPC8572DS and MPC8544DS board.
 This patch fixes this issue.
 For MPC8572
 Port			cfg_io_ports
 PCIE1		0x2, 0x3, 0x7, 0xb, 0xc, 0xf
 PCIE2		0x3, 0x7
 PCIE3		0x7

For MPC8544
Port			cfg_io_ports
PCIE1		0x2, 0x3, 0x4, 0x5, 0x6, 0x7
PCIE2		0x4, 0x5, 0x6, 0x7
PCIE3		0x6, 0x7
