In P2P GO mode, on system suspend to s2idle state, bus
is suspended and D0-WoW is enabled. Ping requests from
P2P client cause the REO interrupt to fire but since
system is in s2idle state, system is not woken-up. This
results in destination unreachability or large rtt for
ping on P2P client.
Fix is to do explicit system wakeup when group interrupts
fire after system is in suspend state.
