[Qemu-devel] [PATCH v2 2/4] pcie: Rename the pcie_cap_ari_* functions to pcie_cap_arifwd_*

[Knut Omang]

Rename helper functions to make a clearer distinction between
the PCIe capability/control register feature ARI forwarding and a
device that supports the ARI feature via an ARI extended PCIe capability.
