[PATCH v2 06/16] hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition

[Thomas Huth <thuth@redhat.com>]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

QEMU_PCIE_EXTCAP_INIT was only used by the hw_compat_2_8[]
array, via the 'x-pcie-extcap-init=off' property. We removed
all machines using that array, let's remove all the code around
QEMU_PCIE_EXTCAP_INIT.

[thuth: Don't remove pci_set_long(), execute it always instead]
