This patch fixes the AMD POGO errata on the hotplug controller where the platform will lock up or reboot if PERR/SERR generation is enabled and a slot is sent an enable command. This fix disables PERR/SERR generation before a slot is sent the enable command by first saving related registers, turning off SERR/PERR generation, enabling the slot, then restoring the registers.
