P9 supports PCI tunneled operations (atomics and as_notify). This
patch adds support for tunneled operations on powernv, with a new
API, to be called by device drivers:
pnv_pci_enable_tunnel()
Enable tunnel operations, tell driver the 16-bit ASN indication
used by kernel.
pnv_pci_disable_tunnel()
Disable tunnel operations.
pnv_pci_set_tunnel_bar()
Tell kernel the Tunnel BAR Response address used by driver.
This function uses two new OPAL calls, as the PBCQ Tunnel BAR
register is configured by skiboot.
pnv_pci_get_as_notify_info()
Return the ASN info of the thread to be woken up.
