This series addresses the limitation and flaw which are occurring due to
ARI capability related bits not set correctly.

First patch addresses the issue of PCI_EXP_DEVCAP2_ARI being not set even
when J7 PCIe controller in RC mode supports ARI Forwarding.

Second patch related to the issue when PCIe controller is put in end point
mode, Next function field in ARI capability for last function stores
current_function+1 value, which is supposed to be zero to signal that
current function is the last one.
