83xx: Remove warmboot parameter from PCI init functions
This change lays the groundwork for the BOOTFLAG_* flags being removed. This change has the small affect of delaying 100ms on PCI initialization after a warm boot as opposed to the optimal 1ms on some boards. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> included the mpc8308_p1m board. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
