PCI/PM: Wrap long lines in documentation 

Documentation/power/pci.rst is wrapped to fit in 80 columns, but directory
structure changes made a few lines longer.  Wrap them so they all fit in 80
columns again.

2.4. System-Wide Power Transitions
----------------------------------
There are a few different types of system-wide power transitions, described in
Documentation/driver-api/pm/devices.rst. Each of them requires devices to be handled
in a specific way and the PM core executes subsystem-level power management
callbacks for this purpose. They are executed in phases such that each phase
involves executing the same subsystem-level callback for every device belonging
to the given subsystem before the next phase begins. These phases always run
after tasks have been frozen.

At the time of this writing there are two ways to define power management
callbacks for a PCI device driver, the recommended one, based on using a
dev_pm_ops structure described in Documentation/driver-api/pm/devices.rst, and the
"legacy" one, in which the .suspend(), .suspend_late(), .resume_early(), and
dev_pm_ops structure described in Documentation/driver-api/pm/devices.rst, and
the "legacy" one, in which the .suspend(), .suspend_late(), .resume_early(), and
.resume() callbacks from struct pci_driver are used. The legacy approach,
however, doesn't allow one to define runtime power management callbacks and is
not really suitable for any new drivers. Therefore it is not covered by this
