There are couple of ways to do it
1)
If you want to disable it runtime, please execute below command

"performance" > /sys/module/pcie_aspm/parameters/policy

To disable at config level, please remove following line from config file

CONFIG_PCIEASPM_POWERSAVE=y

To disable it right from kernel boot add ‘pcie_aspm=off’ to kernel’s command line
