Rafael J. Wysocki fc8fe1e992 PCI / ACPI: Fix build of the AER driver for CONFIG_ACPI unset
After commit 415e12b237 ("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.
