PCI/ASPM: Add missing newline in sysfs 'policy'

BugLink: https://bugs.launchpad.net/bugs/1892822

[ Upstream commit 3167e3d3 ]

When I cat ASPM parameter 'policy' by sysfs, it displays as follows.  Add a
newline for easy reading.  Other sysfs attributes already include a
newline.

  [root@localhost ~]# cat /sys/module/pcie_aspm/parameters/policy
  [default] performance powersave powersupersave [root@localhost ~]#

Fixes: 7d715a6c ("PCI: add PCI Express ASPM support")
