CVE: NA

----------------------------------------------------------------

The kernel driver now will disable interrupt when port is suspended,
causing plugin not work. It is useful to make plugin work，when the
plugin interrupt is enabled with power management status.
Adding pm_request_resume() is to reume port for plugin or PME signal
waking up controller which in D3.

with the AHCI controller frequently enters into D3 and leaves from D3,
the identify cmd may be timeout when controller resumes and establishes
a connect with the device.it is effective to delay 10ms between
controller resume and port resume，with link’s smooth transition.

with non power management request and power management competing with
each other in queue, it is often found that block IO hang 120s when
system disk is suspending or resuming.it is now guaranteed that PM
requests will enter the queue no matter other non-PM requests are
waiting. Increase the pm_only counter before checking whether any
non-PM blk_queue_enter() calls are in progress.
Meanwhile, the new blk_pm_request_resume() call is necessary to occur
during request assigned to a queue when device is suspended.
