intel/lynxpoint: xhci: Revert suspend/resume changes

I have been attempting to work around USB3 issues that appear in the
kernel with hacks in the firmware, but this is resulting in more
headaches in the kernel.

Instead remove all the work that was being done at resume time and undo
the change that was issuing a warm reset to all ports at suspend time.

The bad device behavior will be dealt with at the kernel level to
handle devices that get stuck in polling state after enable/disable
sequence.

BUG=chrome-os-partner:22754
BRANCH=falco,peppy,wolf,leon
TEST=manual:

suspend/resume with several misbehaving devices:
Kingston USB3 Media Reader
Transcend USB3 Media Reader
Various ADATA USB3 drives
Various Kingston USB3 sticks
