Subject: PCI / ACPI: Fix build of the AER driver for !CONFIG_ACPI

After commit 415e12b (PCI/ACPI: Request _OSC control once for each
root bridge (v3)) include/linux/pci-acpi.h is included by
drivers/pci/pcie/aer/aerdrv.c and if CONFIG_ACPI is unset, the
bogus and unnecessary alternative definition of
acpi_find_root_bridge_handle() causes a build error to occur.

Remove the offending piece of garbage.
