lynxpoint: xhci: Port reset changes on suspend/resume

Some USB3 devices are not showing up after suspend/resume cycles.
In particular if a device uses a lower power state like U2 it may
take longer to come up and the firmware needs to wait after sending
a warm port reset.

In addition skipping port reset to connected ports in the way into
suspend was causing problems so instead send all ports a reset
before suspend.

BUG=chrome-os-partner:22402
BRANCH=falco,peppy,leon,wolf
TEST=manual:

Suspend/resume with ADATA HE720 HDD (and other devices) both
connected at suspend and connecting while in suspend and ensure
that the devices always show up in the kernel.
